RFC 5246 7.2.


Field Summary
static short access_denied
          Deprecated. A valid certificate was received, but when access control was applied, the sender decided not to proceed with negotiation.
static short bad_certificate
          Deprecated. A certificate was corrupt, contained signatures that did not verify correctly, etc.
static short bad_certificate_hash_value
          Deprecated. This alert is sent by servers when a certificate hash does not match a client provided certificate_hash.
static short bad_certificate_status_response
          Deprecated. This alert is sent by clients that receive an invalid certificate status response (see Section 3.6).
static short bad_record_mac
          Deprecated. This alert is returned if a record is received with an incorrect MAC.
static short certificate_expired
          Deprecated. A certificate has expired or is not currently valid.
static short certificate_revoked
          Deprecated. A certificate was revoked by its signer.
static short certificate_unknown
          Deprecated. Some other (unspecified) issue arose in processing the certificate, rendering it unacceptable.
static short certificate_unobtainable
          Deprecated. This alert is sent by servers who are unable to retrieve a certificate chain from the URL supplied by the client (see Section 3.3).
static short close_notify
          Deprecated. This message notifies the recipient that the sender will not send any more messages on this connection.
static short decode_error
          Deprecated. A message could not be decoded because some field was out of the specified range or the length of the message was incorrect.
static short decompression_failure
          Deprecated. The decompression function received improper input (e.g., data that would expand to excessive length).
static short decrypt_error
          Deprecated. A handshake cryptographic operation failed, including being unable to correctly verify a signature or validate a Finished message.
static short decryption_failed
          Deprecated. This alert was used in some earlier versions of TLS, and may have permitted certain attacks against the CBC mode [CBCATT].
static short export_restriction
          Deprecated. This alert was used in some earlier versions of TLS.
static short handshake_failure
          Deprecated. Reception of a handshake_failure alert message indicates that the sender was unable to negotiate an acceptable set of security parameters given the options available.
static short illegal_parameter
          Deprecated. A field in the handshake was out of range or inconsistent with other fields.
static short inappropriate_fallback
          Deprecated. If TLS_FALLBACK_SCSV appears in ClientHello.cipher_suites and the highest protocol version supported by the server is higher than the version indicated in ClientHello.client_version, the server MUST respond with a fatal inappropriate_fallback alert [..].
static short insufficient_security
          Deprecated. Returned instead of handshake_failure when a negotiation has failed specifically because the server requires ciphers more secure than those supported by the client.
static short internal_error
          Deprecated. An internal error unrelated to the peer or the correctness of the protocol (such as a memory allocation failure) makes it impossible to continue.
static short no_certificate
          Deprecated. This alert was used in SSLv3 but not any version of TLS.
static short no_renegotiation
          Deprecated. Sent by the client in response to a hello request or by the server in response to a client hello after initial handshaking.
static short protocol_version
          Deprecated. The protocol version the client has attempted to negotiate is recognized but not supported.
static short record_overflow
          Deprecated. A TLSCiphertext record was received that had a length more than 2^14+2048 bytes, or a record decrypted to a TLSCompressed record with more than 2^14+1024 bytes.
static short unexpected_message
          Deprecated. An inappropriate message was received.
static short unknown_ca
          Deprecated. A valid certificate chain or partial chain was received, but the certificate was not accepted because the CA certificate could not be located or couldn't be matched with a known, trusted CA.
static short unknown_psk_identity
          Deprecated. If the server does not recognize the PSK identity, it MAY respond with an "unknown_psk_identity" alert message.

static short unsupported_certificate
          Deprecated. A certificate was of an unsupported type.
static short unsupported_extension
          Deprecated. Sent by clients that receive an extended server hello containing an extension that they did not put in the corresponding client hello.

Field Detail

close_notify

public static final short close_notify
Deprecated. 
This message notifies the recipient that the sender will not send any more messages on this connection. Note that as of TLS 1.1, failure to properly close a connection no longer requires that a session not be resumed. This is a change from TLS 1.0 ("The session becomes unresumable if any connection is terminated without proper close_notify messages with level equal to warning.") to conform with widespread implementation practice.

unexpected_message

public static final short unexpected_message
Deprecated. 
An inappropriate message was received. This alert is always fatal and should never be observed in communication between proper implementations.

bad_record_mac

public static final short bad_record_mac
Deprecated. 
This alert is returned if a record is received with an incorrect MAC. This alert also MUST be returned if an alert is sent because a TLSCiphertext decrypted in an invalid way: either it wasn't an even multiple of the block length, or its padding values, when checked, weren't correct. This message is always fatal and should never be observed in communication between proper implementations (except when messages were corrupted in the network).

decryption_failed

public static final short decryption_failed
Deprecated. 
This alert was used in some earlier versions of TLS, and may have permitted certain attacks against the CBC mode [CBCATT]. It MUST NOT be sent by compliant implementations.

record_overflow

public static final short record_overflow
Deprecated. 
A TLSCiphertext record was received that had a length more than 2^14+2048 bytes, or a record decrypted to a TLSCompressed record with more than 2^14+1024 bytes. This message is always fatal and should never be observed in communication between proper implementations (except when messages were corrupted in the network).

decompression_failure

public static final short decompression_failure
Deprecated. 
The decompression function received improper input (e.g., data that would expand to excessive length). This message is always fatal and should never be observed in communication between proper implementations.

handshake_failure

public static final short handshake_failure
Deprecated. 
Reception of a handshake_failure alert message indicates that the sender was unable to negotiate an acceptable set of security parameters given the options available. This is a fatal error.

no_certificate

public static final short no_certificate
Deprecated. 
This alert was used in SSLv3 but not any version of TLS. It MUST NOT be sent by compliant implementations.

bad_certificate

public static final short bad_certificate
Deprecated. 
A certificate was corrupt, contained signatures that did not verify correctly, etc.

unsupported_certificate

public static final short unsupported_certificate
Deprecated. 
A certificate was of an unsupported type.

certificate_revoked

public static final short certificate_revoked
Deprecated. 
A certificate was revoked by its signer.

certificate_expired

public static final short certificate_expired
Deprecated. 
A certificate has expired or is not currently valid.

certificate_unknown

public static final short certificate_unknown
Deprecated. 
Some other (unspecified) issue arose in processing the certificate, rendering it unacceptable.

illegal_parameter

public static final short illegal_parameter
Deprecated. 
A field in the handshake was out of range or inconsistent with other fields. This message is always fatal.

unknown_ca

public static final short unknown_ca
Deprecated. 
A valid certificate chain or partial chain was received, but the certificate was not accepted because the CA certificate could not be located or couldn't be matched with a known, trusted CA. This message is always fatal.

access_denied

public static final short access_denied
Deprecated. 
A valid certificate was received, but when access control was applied, the sender decided not to proceed with negotiation. This message is always fatal.

decode_error

public static final short decode_error
Deprecated. 
A message could not be decoded because some field was out of the specified range or the length of the message was incorrect. This message is always fatal and should never be observed in communication between proper implementations (except when messages were corrupted in the network).

decrypt_error

public static final short decrypt_error
Deprecated. 
A handshake cryptographic operation failed, including being unable to correctly verify a signature or validate a Finished message. This message is always fatal.

export_restriction

public static final short export_restriction
Deprecated. 
This alert was used in some earlier versions of TLS. It MUST NOT be sent by compliant implementations.

protocol_version

public static final short protocol_version
Deprecated. 
The protocol version the client has attempted to negotiate is recognized but not supported. (For example, old protocol versions might be avoided for security reasons.) This message is always fatal.

insufficient_security

public static final short insufficient_security
Deprecated. 
Returned instead of handshake_failure when a negotiation has failed specifically because the server requires ciphers more secure than those supported by the client. This message is always fatal.

internal_error

public static final short internal_error
Deprecated. 
An internal error unrelated to the peer or the correctness of the protocol (such as a memory allocation failure) makes it impossible to continue. This message is always fatal.

user_canceled

public static final short user_canceled
Deprecated. 
This handshake is being canceled for some reason unrelated to a protocol failure. If the user cancels an operation after the handshake is complete, just closing the connection by sending a close_notify is more appropriate. This alert should be followed by a close_notify. This message is generally a warning.

no_renegotiation

public static final short no_renegotiation
Deprecated. 
Sent by the client in response to a hello request or by the server in response to a client hello after initial handshaking. Either of these would normally lead to renegotiation; when that is not appropriate, the recipient should respond with this alert. At that point, the original requester can decide whether to proceed with the connection. One case where this would be appropriate is where a server has spawned a process to satisfy a request; the process might receive security parameters (key length, authentication, etc.) at startup, and it might be difficult to communicate changes to these parameters after that point. This message is always a warning.

unsupported_extension

public static final short unsupported_extension
Deprecated. 
Sent by clients that receive an extended server hello containing an extension that they did not put in the corresponding client hello. This message is always fatal.

certificate_unobtainable

public static final short certificate_unobtainable
Deprecated. 
This alert is sent by servers who are unable to retrieve a certificate chain from the URL supplied by the client (see Section 3.3). This message MAY be fatal - for example if client authentication is required by the server for the handshake to continue and the server is unable to retrieve the certificate chain, it may send a fatal alert.

unrecognized_name

public static final short unrecognized_name
Deprecated. 
This alert is sent by servers that receive a server_name extension request, but do not recognize the server name. This message MAY be fatal.

bad_certificate_status_response

public static final short bad_certificate_status_response
Deprecated. 
This alert is sent by clients that receive an invalid certificate status response (see Section 3.6). This message is always fatal.

bad_certificate_hash_value

public static final short bad_certificate_hash_value
Deprecated. 
This alert is sent by servers when a certificate hash does not match a client provided certificate_hash. This message is always fatal.

unknown_psk_identity

public static final short unknown_psk_identity
Deprecated. 
If the server does not recognize the PSK identity, it MAY respond with an "unknown_psk_identity" alert message.

inappropriate_fallback

public static final short inappropriate_fallback
Deprecated. 
If TLS_FALLBACK_SCSV appears in ClientHello.cipher_suites and the highest protocol version supported by the server is higher than the version indicated in ClientHello.client_version, the server MUST respond with a fatal inappropriate_fallback alert [..].
