Method Detail

getPrivateKeyFromPEM

public ECPrivateKey getPrivateKeyFromPEM(String key)
                                  throws IOException,
                                         InvalidKeySpecException

Decode the PEM encoded elliptic curve private key into an ECPrivateKey.

Parameters:

key - the PEM encoded elliptic curve private key

Returns:

the ECPrivateKey

Throws:

IOException - thrown if there is an IO issue processing the encoded key

InvalidKeySpecException - thrown is the key is not the expected format and specification

getPrivateKeyFromPKCS8

public ECPrivateKey getPrivateKeyFromPKCS8(byte[] key)
                                    throws InvalidKeySpecException

Decode the PKCS8 encoded elliptic curve private key into an ECPrivateKey.

Parameters:

key - the PKCS8 encoded elliptic curve private key

Returns:

the ECPrivateKey

Throws:

InvalidKeySpecException - thrown is the key is not the expected format and specification

getPublicKeyFromPEM

public ECPublicKey getPublicKeyFromPEM(String key)
                                throws IOException,
                                       InvalidKeySpecException

Decode the PEM encoded elliptic curve public key into an ECPublicKey.

Parameters:

key - the PEM encoded elliptic curve public key

Returns:

the ECPublicKey

Throws:

IOException - thrown if there is an IO issue processing the encoded key

InvalidKeySpecException - thrown is the key is not the expected format and specification

getPublicKeyFromX509

public ECPublicKey getPublicKeyFromX509(byte[] key)
                                 throws InvalidKeySpecException

Decode the X509 encoded elliptic curve public key into an ECPublicKey.

Parameters:

key - the X509 encoded elliptic curve public key
