HMAC Knowledge
What is HMAC?
HMAC is a keyed-hash message authentication code that combines a hash function with a secret key.
Security
HMAC security depends on the strength of the hash function and the secrecy of the key.
HMAC-MD5
HMAC implementation based on MD5, generating 128-bit (16-byte) authentication codes. While the underlying MD5 algorithm has security concerns, it's still considered secure within the HMAC construction. Suitable for scenarios requiring fast processing.
HMAC-SHA1
HMAC implementation based on SHA-1, generating 160-bit (20-byte) authentication codes. Although SHA-1 itself is no longer recommended for digital signatures, it remains secure when used in HMAC.
HMAC-SHA224
HMAC implementation based on SHA-224, generating 224-bit (28-byte) authentication codes. Member of the SHA-2 family, providing higher security than SHA-1. Suitable for scenarios requiring both performance and security.
HMAC-SHA256
HMAC implementation based on SHA-256, generating 256-bit (32-byte) authentication codes. Currently the most widely used HMAC algorithm, employed in TLS, SSH, and other security protocols. Provides a good balance of security and performance.
HMAC-SHA384
HMAC implementation based on SHA-384, generating 384-bit (48-byte) authentication codes. Provides stronger security guarantees than SHA-256, suitable for enterprise applications requiring higher security levels.
HMAC-SHA512
HMAC implementation based on SHA-512, generating 512-bit (64-byte) authentication codes. The most secure version in the SHA-2 family, suitable for scenarios with extremely high security requirements.
HMAC-SHA3-224
HMAC implementation based on SHA3-224, generating 224-bit (28-byte) authentication codes. Uses the next-generation SHA-3 hash standard, providing different security characteristics than SHA-2.
HMAC-SHA3-256
HMAC implementation based on SHA3-256, generating 256-bit (32-byte) authentication codes. The most commonly used version in the SHA-3 standard, designed to replace the SHA-2 series.
HMAC-SHA3-384
HMAC implementation based on SHA3-384, generating 384-bit (48-byte) authentication codes. High-strength version of the SHA-3 family, suitable for applications requiring long-term security guarantees.
HMAC-SHA3-512
HMAC implementation based on SHA3-512, generating 512-bit (64-byte) authentication codes. The most secure version in the SHA-3 family, providing the highest level of security protection.
HMAC-RIPEMD160
HMAC implementation based on RIPEMD160, generating 160-bit (20-byte) authentication codes. Provides unique security characteristics, used in specific scenarios.
