func DERKeyTemplate ¶

func DERKeyTemplate() (*tinkpb.KeyTemplate, error)

DERKeyTemplate is a KeyTemplate that generates a new ECDSA secp256k1 private key with the following parameters:

• Hash function: SHA256
• Curve: secp256k1
• Signature encoding: DER
• Output prefix type: TINK

func IEEEP1363KeyTemplate ¶

func IEEEP1363KeyTemplate() (*tinkpb.KeyTemplate, error)

IEEEP1363KeyTemplate is a KeyTemplate that generates a new ECDSA secp256k1 private key with the following parameters:

• Hash function: SHA256
• Curve: secp256k1
• Signature encoding: IEEE-P1363
• Output prefix type: TINK

func NewSigner ¶

func NewSigner(h *keyset.Handle) (tink.Signer, error)

NewSigner returns a Signer primitive from the given keyset handle.

func NewSignerWithKeyManager ¶

func NewSignerWithKeyManager(h *keyset.Handle, km registry.KeyManager) (tink.Signer, error)

NewSignerWithKeyManager returns a Signer primitive from the given keyset handle and custom key manager. Deprecated: register the KeyManager and use New above.

func NewVerifier ¶

func NewVerifier(h *keyset.Handle) (tink.Verifier, error)

NewVerifier returns a Verifier primitive from the given keyset handle.

func NewVerifierWithKeyManager ¶

func NewVerifierWithKeyManager(h *keyset.Handle, km registry.KeyManager) (tink.Verifier, error)

NewVerifierWithKeyManager returns a Verifier primitive from the given keyset handle and custom key manager. Deprecated: register the KeyManager and use New above.

func ValidateSecp256K1Params ¶

func ValidateSecp256K1Params(hashAlg, curve, encoding string) error

ValidateSecp256K1Params validates ECDSA parameters. The hash's strength must not be weaker than the curve's strength. DER and IEEE_P1363 encodings are supported.
