Method Detail

getAlgId

public String getAlgId()

Get the SPKI encryption/signature algorithm id associated with the key.

Returns:

String containing a SPKI algorithm-id.

getJCAKey

public Key getJCAKey()

Get a key object usable by [I]JCA packages.

Returns:

java.security.Key object implementing, or null if this is a private key.

getKeyHash

public Hash getKeyHash()
                throws SPKIException

Get a Hash representing this key using the default hash algorithm.

Returns:

Hash object representing this key.

Throws:

SPKIException - if something went wrong

getKeyHash

public Hash getKeyHash(String hashAlg)
                throws SPKIException

Get a Hash representing this key using the specified hashing algorithm.

Parameters:

hashAlg - hashing algorithm-id to use.

Returns:

Hash object representing this key.

Throws:

SPKIException - if something went wrong

getKeyId

public String getKeyId()
                throws SPKIException

Get the key-id of this key. Key-id is a Base64-encoded hash value, using the default hash algorithm.

Returns:

String containing the key-id, or null.

Throws:

SPKIException - if something went wrong
