FSharp.ATProto

Signing Module

Namespace: FSharp.ATProto.Crypto
Assembly: FSharp.ATProto.Crypto.dll

ECDSA signing and verification with low-S normalization as required by AT Protocol. All signatures use compact format (64 bytes: r || s, 32 bytes each).

Functions and values

Function or value	Description
`sign keyPair data` Full Usage: `sign keyPair data` Parameters: keyPair : `KeyPair` data : `byte[]` Returns: `byte[]`	Sign data with a key pair. Returns a 64-byte compact signature with low-S. The data is hashed with SHA-256 internally. keyPair : `KeyPair` data : `byte[]` Returns: `byte[]`
`verify publicKey data signature` Full Usage: `verify publicKey data signature` Parameters: publicKey : `PublicKey` data : `byte[]` signature : `byte[]` Returns: `bool`	Verify a compact signature against data and a public key. Enforces low-S requirement. Returns false for high-S or DER-encoded signatures. publicKey : `PublicKey` data : `byte[]` signature : `byte[]` Returns: `bool`
