Enclosing class:

DigitalSignature

public static class DigitalSignature.WithKey
extends DigitalSignature

A digital signature that identifies who the public key is owned by.

Constructor Detail

WithKey

public WithKey(@NotNull
               java.security.PublicKey by,
               @NotNull
               kotlin.Array[] bytes)

A digital signature that identifies who the public key is owned by.

Method Detail

verify

public boolean verify(@NotNull
                      kotlin.Array[] content)

Utility to simplify the act of verifying a signature.

Throws:

InvalidKeyException - if the key to verify the signature with is not valid (i.e. wrong key type for the signature).

SignatureException - if the signature is invalid (i.e. damaged), or does not match the key (incorrect).

verify

public boolean verify(@NotNull
                      OpaqueBytes content)

Utility to simplify the act of verifying a signature.

Throws:

InvalidKeyException - if the key to verify the signature with is not valid (i.e. wrong key type for the signature).

SignatureException - if the signature is invalid (i.e. damaged), or does not match the key (incorrect).

isValid

public boolean isValid(@NotNull
                       kotlin.Array[] content)

Utility to simplify the act of verifying a signature. In comparison to verify doesn't throw an exception, making it more suitable where a boolean is required, but normally you should use the function which throws, as it avoids the risk of failing to test the result.

Returns:

whether the signature is correct for this key.

Throws:

InvalidKeyException - if the key to verify the signature with is not valid (i.e. wrong key type for the signature).

SignatureException - if the signature is invalid (i.e. damaged).
