micro509/crypto

Canonical detached-signature crypto surface. Owns raw sign/verify primitives and ECDSA signature encoding conversion.

Functions

• ecdsaSignatureDerToRaw — Converts a DER ECDSA-Sig-Value (RFC 5480: SEQUENCE of INTEGERs r and s)
• ecdsaSignatureRawToDer — Converts a fixed-width raw r || s ECDSA signature to the DER
• signData — Signs data with a WebCrypto private key and returns the signature beside
• verifySignature — Verifies a detached signature against the signer's DER SubjectPublicKeyInfo.
• verifySignatureWithKey — Verifies a detached signature using an existing WebCrypto public key without

Types

• SignatureProfileInput — Controls how the signature algorithm is chosen.
• SignDataResult — Result of signData: the signature plus its on-wire algorithm identity.
• VerifySignatureConfigFailure — Failure: the signature algorithm or its parameters are not supported.
• VerifySignatureInput — Input for verifySignature.
• VerifySignatureLimitFailure — Failure: the signature algorithm parameters exceed a micro509 decoding limit.
• VerifySignatureResult — Result of verifySignature and verifySignatureWithKey.
• VerifySignatureWithKeyInput — Input for verifySignatureWithKey.
• VerifySignedDataFailure — Failure: signature verification could not run to completion.
• VerifySignedDataResult — Result of a full signature verification: validity, unsupported params, or a runtime verification failure.
• VerifySignedDataSuccess — Success branch of VerifySignedDataResult.
