Name	Value	Description
Aes128_Sha256_RsaOaepsince v2.52	7	TODO
Aes256_Sha256_RsaPsssince v2.52	8	TODO
Auto	0	The Algorithm and Uri used by a OpcSecurityPolicy is determined according to the OpcSecurityMode used: None for the mode None and Basic256Sha256 for the modes Sign and SignAndEncrypt. The algorithms Basic128Rsa15 and Basic256 are deprecated by OPC 10000-7 and therefore only used if stated explicitly.
Basic128Rsa15	3	The URI 'http://opcfoundation.org/UA/SecurityPolicy#Basic128Rsa15' is used by the Uri of a OpcSecurityPolicy and expresses the use of (not longer secure) security using RSA-15 as the key wrap algorithm and 128-bit Basic for message encryption.
Basic256	4	The URI 'http://opcfoundation.org/UA/SecurityPolicy#Basic256' is used by the Uri of a OpcSecurityPolicy and expresses the use of security using 256-bit Basic for message encryption.
Basic256Sha256	5	The URI 'http://opcfoundation.org/UA/SecurityPolicy#Basic256Sha256' is used by the Uri of a OpcSecurityPolicy and expresses the use of security using SHA-256 for the signature digest and 256-bit Basic for message encryption.
Custom	1	The Algorithm referred to by Uri used by a OpcSecurityPolicy does not refer to one of the OPC UA predefined security policies.
Https	6	The URI 'http://opcfoundation.org/UA/SecurityPolicy#Https' is used by the Uri of a OpcSecurityPolicy and expresses the use of security using an encryption layer of SSL/TLS to protect messages. ATTENTION: This security algorithm is (not) yet supported by OPC UA.
None	2	The URI 'http://opcfoundation.org/UA/SecurityPolicy#None' is used by the Uri of a OpcSecurityPolicy and expresses that no security is to be used.
