getPrivateKey

public static PrivateKey getPrivateKey(String privateKeyPKCS8)
                                throws NoSuchAlgorithmException,
                                       InvalidKeySpecException

Generate a PrivateKey from a Base64 encoded private key. In order to generate a valid PKCS8 key when you have a PEM key you can do this: openssl pkcs8 -topk8 -inform PEM -in rsapriv.pem -outform DER -nocrypt -out rsapriv.der And then base64 encode the content.

Parameters:

privateKeyPKCS8 - a Base64 encoded string of the RSA key in PKCS8 format

Returns:

the PrivateKey

Throws:

NoSuchAlgorithmException - if RSA is unknown

InvalidKeySpecException - on bad input key
