    • getAliasForX509Cert

      public String getAliasForX509Cert(Certificate cert) throws WSSecurityException
      Return a X509 Certificate alias in the keystore according to a given Certificate

      Specified by:
      getAliasForX509Cert in interface Crypto
      Parameters:
      cert - The certificate to lookup
      Returns:
      alias name of the certificate that matches the given certificate or null if no such certificate was found.
      Throws:

    • getDefaultX509Alias

      public String getDefaultX509Alias()
      Retrieves the alias name of the default certificate which has been specified as a property. This should be the certificate that is used for signature and encryption. This alias corresponds to the certificate that should be used whenever KeyInfo is not poresent in a signed or an encrypted message. May return null.
      Specified by:
      getDefaultX509Alias in interface Crypto

      If the the certificate does not contain a SKI extension then try to compute the SKI according to RFC3280 using the SHA-1 hash value of the public key. The second method described in RFC3280 is not support. Also only RSA public keys are supported. If we cannot compute the SKI throw a WSSecurityException.
