Supported Algorithms

Algorithm Endpoint Output format Notes
md5 /v1/hash hex / base64 Fast, not collision-resistant
sha256 /v1/hash, /v1/hmac, /v1/verify hex / base64 Recommended for integrity checks
sha512 /v1/hash, /v1/hmac, /v1/verify hex / base64 Higher security margin than SHA256
blake3 /v1/hash, /v1/hmac, /v1/verify hex / base64 Fastest, modern, highly parallelizable
bcrypt /v1/hash, /v1/verify encoded string Password hashing, adaptive cost (cost=12)
argon2 /v1/hash, /v1/verify encoded string Password hashing, memory-hard (Argon2id)
