Method Detail

generatePublic

public java.security.PublicKey generatePublic(java.security.spec.KeySpec keySpec)
                                       throws java.security.spec.InvalidKeySpecException

Converts, if possible, a key specification into a BCMcEliecePublicKey. Currently, the following key specifications are supported: McEliecePublicKeySpec, X509EncodedKeySpec.

Parameters:

keySpec - the key specification

Returns:

the McEliece public key

Throws:

java.security.spec.InvalidKeySpecException - if the key specification is not supported.

generatePrivate

public java.security.PrivateKey generatePrivate(java.security.spec.KeySpec keySpec)
                                         throws java.security.spec.InvalidKeySpecException

Converts, if possible, a key specification into a BCMcEliecePrivateKey. Currently, the following key specifications are supported: McEliecePrivateKeySpec, PKCS8EncodedKeySpec.

Parameters:

keySpec - the key specification

Returns:

the McEliece private key

Throws:

java.security.spec.InvalidKeySpecException - if the KeySpec is not supported.

getKeySpec

public java.security.spec.KeySpec getKeySpec(java.security.Key key,
                                             java.lang.Class keySpec)
                                      throws java.security.spec.InvalidKeySpecException

Converts, if possible, a given key into a key specification. Currently, the following key specifications are supported:

• for McEliecePublicKey: X509EncodedKeySpec, McEliecePublicKeySpec
• for McEliecePrivateKey: PKCS8EncodedKeySpec, McEliecePrivateKeySpec
.

Parameters:

key - the key

keySpec - the key specification

Returns:

the specification of the McEliece key

Throws:

java.security.spec.InvalidKeySpecException - if the key type or the key specification is not supported.

Parameters:

key - the key

Returns:

a key of a known key type

Throws:

java.security.InvalidKeyException - if the key type is not supported.
