Method Summary

Methods

Modifier and Type	Method and Description
boolean	canSign()
boolean	canVerify()
Set<Algorithm>	getAlgorithms()
String	getId()
byte[]	sign(Algorithm algorithm, byte[] contentBytes) Signs the challengeHash using the specified signature Algorithm
boolean	verify(Algorithm algorithm, byte[] contentBytes, byte[] signatureBytes) Verifies the signatureBytes against the challengeHash using an underlying public key

Method Detail

getId

String getId()

Returns:

the Key's self-identification. This may end up not being unique within a keychain.

getAlgorithms

Set<Algorithm> getAlgorithms()

Returns:

the Set of Signature Algorithms supported by this key.

canVerify

boolean canVerify()

Returns:

true if this Key can be used for verification

verify

boolean verify(Algorithm algorithm,
             byte[] contentBytes,
             byte[] signatureBytes)

Verifies the signatureBytes against the challengeHash using an underlying public key

Parameters:

algorithm - the selected Signature Algorithm

contentBytes - the result of SignatureBuilder.buildContent(java.util.List, java.nio.charset.Charset)

signatureBytes - the result of Authorization.getSignatureBytes()

Returns:

true if signature is valid

canSign

boolean canSign()

Returns:

true if this Key can be used for signing

sign

byte[] sign(Algorithm algorithm,
          byte[] contentBytes)

Signs the challengeHash using the specified signature Algorithm

Parameters:

algorithm - the selected Signature Algorithm

contentBytes - the result of SignatureBuilder.buildContent(java.util.List, java.nio.charset.Charset)

Returns:

byte array containing the challengeHash signature or null if a signature could not be generated.
