Constructor Detail

SSHKey

public SSHKey(KeyFormat keyFormat,
              KeyPair keyPair)

SSHKey

public SSHKey(KeyFormat keyFormat,
              PublicKey publicKey,
              PrivateKey privateKey)

Method Detail

getId

public String getId()

Specified by:

getId in interface Key

Returns:

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

getFingerprint

public String getFingerprint()

Specified by:

getFingerprint in interface FingerprintableKey

Returns:

the public key fingerprint

getAlgorithms

public Set<Algorithm> getAlgorithms()

Specified by:

getAlgorithms in interface Key

Returns:

the Set of Signature Algorithms supported by this key.

canVerify

public boolean canVerify()

Specified by:

canVerify in interface Key

Returns:

true if this Key can be used for verification

canSign

public boolean canSign()

Specified by:

canSign in interface Key

Returns:

true if this Key can be used for signing

verify

public boolean verify(Algorithm algorithm,
                      byte[] challengeHash,
                      byte[] signatureBytes)

Verifies the signatureBytes against the challengeHash using an underlying public key

Specified by:

verify in interface Key

Parameters:

algorithm - the selected Signature Algorithm

challengeHash - the result of RequestContent.getBytesToSign(java.util.List, java.nio.charset.Charset)

signatureBytes - the result of Authorization.getSignatureBytes()

Returns:

true if signature is valid

sign

public byte[] sign(Algorithm algorithm,
                   byte[] challengeHash)

Signs the challengeHash using the specified signature Algorithm

Specified by:

sign in interface Key

Parameters:

algorithm - the selected Signature Algorithm

challengeHash - the result of RequestContent.getBytesToSign(java.util.List, java.nio.charset.Charset)

Returns:

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

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
