6979
RFC 6979 defines deterministic ECDSA.

Where 6979 fits
Why 6979 is special
It exists because a reused random value in an ECDSA signature reveals the private key outright, which is how several real key compromises happened.

Technology & computing
RFC 6979 specifies deriving the ECDSA nonce deterministically from the message and private key. Repeated or predictable nonces allow direct private key recovery, a failure observed in deployed systems.
