SNMPv3 supports the following authentication algorithms:
1. HMAC-MD5-96: This algorithm uses a 128-bit secret key and computes a message digest of 96 bits using the MD5 hashing algorithm.
1. HMAC-SHA-96: This algorithm uses a 160-bit secret key and computes a message digest of 96 bits using the SHA-1 hashing algorithm.
1. HMAC-SHA-224-128: This algorithm uses a 192-bit secret key and computes a message digest of 128 bits using the SHA-224 hashing algorithm.
1. HMAC-SHA-256-192: This algorithm uses a 256-bit secret key and computes a message digest of 192 bits using the SHA-256 hashing algorithm.
1. HMAC-SHA-384-256: This algorithm uses a 384-bit secret key and computes a message digest of 256 bits using the SHA-384 hashing algorithm.
1. HMAC-SHA-512-384: This algorithm uses a 512-bit secret key and computes a message digest of 384 bits using the SHA-512 hashing algorithm.
