Module tink_signature::subtle

This module provides subtle implementations of digital signature primitives.

Structs

• EcdsaSigner
  EcdsaSigner is an implementation of tink_core::Signer for ECDSA. At the moment, the implementation only accepts DER encoding.
• EcdsaVerifier
  EcdsaVerifier is an implementation of tink_core::Verifier for ECDSA. At the moment, the implementation only accepts signatures with strict DER encoding.
• Ed25519Signer
  A Signer implementation for ED25519.
• Ed25519Verifier
  A tink_core::Verifier for ED25519.

Enums

• EcdsaPrivateKey
  An ECDSA private key.
• EcdsaPublicKey
  An ECDSA public key.
• SignatureEncoding
  Supported signature encodings. This is a precise subset of the protobuf enum, allowing exact matches.

Functions

• element_from_padded_slice
  Produce an elliptic field element from a byte slice, allowing for padding
• validate_ecdsa_params
  Validate ECDSA parameters. The hash’s strength must not be weaker than the curve’s strength. DER and IEEE_P1363 encodings are supported.
