ECHO

Compare Algorithms Benchmark Performance Start Challenge

ECHO

SHA-3 finalist (2008). BIG-AES compression paradigm: AES round components applied to 4×4 matrix of 128-bit (ECHO-256) or 256-bit (ECHO-512) words. Wide-pipe design with 2048/4096-bit internal state.

Legacyhash

Plaintext / Input Message

Cryptographic Key / Shift

Auto Compute

Generated Hash DigestLocally Derived

No output yet

Include key & secrets in export (educational mode)

Imported traces are validated and replayed locally. They never run a cipher operation automatically.

Recommended Next Step

Continue your cryptography learning path

BLAKE2b-256

Secure

RFC 7693 hash function — faster than MD5/SHA-2 while at least as secure as SHA-3, with a natively built-in keyed-MAC mode (no HMAC construction needed).
