Method Detail

savePublicKey

public static byte[] savePublicKey(org.bouncycastle.jce.interfaces.ECPublicKey publicKey)

Get the uncompressed encoding of the public key point. The resulting array should be 65 bytes length and start with 0x04 followed by the x and y coordinates (32 bytes each).

Parameters:

publicKey -

Returns:

savePrivateKey

public static byte[] savePrivateKey(org.bouncycastle.jce.interfaces.ECPrivateKey privateKey)

base64Decode

public static byte[] base64Decode(java.lang.String base64Encoded)

Base64-decode a string. Works for both url-safe and non-url-safe encodings.

Parameters:

base64Encoded -

Returns:

loadPublicKey

public static java.security.PublicKey loadPublicKey(java.lang.String encodedPublicKey)
                                             throws java.security.NoSuchProviderException,
                                                    java.security.NoSuchAlgorithmException,
                                                    java.security.spec.InvalidKeySpecException

Load the public key from a URL-safe base64 encoded string. Takes into account the different encodings, including point compression.

Parameters:

encodedPublicKey -

Throws:

java.security.NoSuchProviderException

loadPrivateKey

public static java.security.PrivateKey loadPrivateKey(java.lang.String encodedPrivateKey)
                                               throws java.security.NoSuchProviderException,
                                                      java.security.NoSuchAlgorithmException,
                                                      java.security.spec.InvalidKeySpecException
