decodePublicKey

@JvmStatic fun decodePublicKey(encodedKey: ByteArray): PublicKey

Decode an X509 encoded key to its PublicKey object. Use this method if the key type is a-priori unknown.

Parameters

encodedKey - an X509 encoded public key.

Exceptions

IllegalArgumentException - on not supported scheme or if the given key specification is inappropriate for this key factory to produce a private key.

@JvmStatic fun decodePublicKey(schemeCodeName: String, encodedKey: ByteArray): PublicKey

Decode an X509 encoded key to its PrivateKey object based on the input scheme code name. This should be used when the type key is known, e.g. during deserialisation or with key caches or key managers.

Parameters

schemeCodeName - a String that should match a key in supportedSignatureSchemes map (e.g. ECDSA_SECP256K1_SHA256).

encodedKey - an X509 encoded public key.

Exceptions

IllegalArgumentException - if the requested scheme is not supported.

InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a public key.

@JvmStatic fun decodePublicKey(signatureScheme: SignatureScheme, encodedKey: ByteArray): PublicKey

Decode an X509 encoded key to its PrivateKey object based on the input scheme code name. This should be used when the type key is known, e.g. during deserialisation or with key caches or key managers.

Parameters

signatureScheme - a signature scheme (e.g. ECDSA_SECP256K1_SHA256).

encodedKey - an X509 encoded public key.

Exceptions

IllegalArgumentException - if the requested scheme is not supported.

InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a public key.
