Security Basic 256 A suite of algorithms that are for 256-Bit (32 bytes) encryption, algorithms include: - SymmetricSignatureAlgorithm - HmacSha1 (http://www.w3.org/2000/09/xmldsig#hmac-sha1) - SymmetricEncryptionAlgorithm - Aes256 (http://www.w3.org/2001/04/xmlenc#aes256-cbc) - AsymmetricSignatureAlgorithm - RsaSha1 (http://www.w3.org/2000/09/xmldsig#rsa-sha1) - AsymmetricKeyWrapAlgorithm - KwRsaOaep (http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p) - AsymmetricEncryptionAlgorithm - RsaOaep (http://www.w3.org/2001/04/xmlenc#rsa-oaep) - KeyDerivationAlgorithm - PSha1 (http://docs.oasis-open.org/ws-sx/ws-secureconversation/200512/dk/p_sha1) - DerivedSignatureKeyLength - 192 (24 bytes) - MinAsymmetricKeyLength - 1024 (128 bytes) - MaxAsymmetricKeyLength - 2048 (256 bytes) - CertificateSignatureAlgorithm - Sha1 If a certificate or any certificate in the chain is not signed with a hash that is Sha1 or stronger then the certificate shall be rejected.
