Instance Methodswift-crypto 3.8.0Crypto
signature(for:)
Generates an Elliptic Curve Digital Signature Algorithm (ECDSA) signature of the digest you provide over the P-521 elliptic curve.
ECDSA.swift:468func signature<D>(for digest: D) throws -> P521.Signing.ECDSASignature where D : Digest Parameters
- digest
The digest of the data to sign.
Returns
The signature corresponding to the digest. The signing algorithm employs randomization to generate a different signature on every call, even for the same data and key.
