iaik.security.ssl
Class SignatureAndHashAlgorithm

java.lang.Object
  extended by iaik.security.ssl.SignatureAndHashAlgorithm
All Implemented Interfaces:
java.lang.Cloneable
Direct Known Subclasses:
SignatureScheme
public class SignatureAndHashAlgorithm
extends java.lang.Object
implements java.lang.Cloneable

Implements the TLS 1.2 SignatureAndHashAlgorithm structure as specified by RFC 5246.

Note that TLS 1.3 (RFC 8446) replaces the SignatureAndHashAlgorithm type by the SignatureScheme type. For compatibility reasons iSaSiLk can be used with both types, SignatureAndHashAlgorithm and SignatureScheme.

A TLS 1.2 client/server may use the SignatureAndHashAlgorithm structure to announce the signature/hash algorithms it is able to support to the peer. The client, for instance, may send a SignatureAlgorithms extension with the ClientHello extension list to tell the server which SignatureAndHashAlgorithms the client can process to, e.g., verify the server certificates or, e.g., sign the CertificateVerify message.
The server, for instance, will specify a list of expected SignatureAndHashAlgorithms when sending the CertificateRequest message.

Each SignatureAndHashAlgorithm elements is composed of an pair of hash and corresponding signature algorithm: 

    enum {
        none(0), md5(1), sha1(2), sha224(3), sha256(4), sha384(5),
        sha512(6), (255)
    } HashAlgorithm;
 
     enum { anonymous(0), rsa(1), dsa(2), ecdsa(3), (255) }
       SignatureAlgorithm;
 
     struct {
          HashAlgorithm hash;
          SignatureAlgorithm signature;
    } SignatureAndHashAlgorithm;
 
    SignatureAndHashAlgorithm
      supported_signature_algorithms<2..2^16-2>;
The following SignatureAndHash algorithms are supported by iSaSiLk:
