Input

Algorithms

Common
SHA-3 / Keccak / SHAKE
SHAKE are XOFs; current output length = 256 bits.
Blake / xxHash
Key-derivation / Password hashing
PBKDF2-HMAC-SHA256
Argon2id
scrypt
bcrypt
KDFs output a PHC/MCF string for interoperability (bcrypt uses MCF).
āš ļø MD5/SHA-1 are not collision-resistant. Avoid them for security-sensitive use.

Verification

KDF Verify (PHC/MCF)

Results

AlgorithmHash (hex / PHC / MCF)Match

PBKDF2-HMAC-SHA256

Argon2id

scrypt

bcrypt

Note: bcrypt uses only the first 72 bytes of the password.
