  • All Implemented Interfaces:
    KeySpec
    Direct Known Subclasses:
    OpenSSHPrivateKeySpec

    public class OpenSSHPrivateKeySpec
    extends EncodedKeySpec
    OpenSSHPrivateKeySpec holds and encoded OpenSSH private key. The format of the key can be either ASN.1 or OpenSSH.

      • OpenSSHPrivateKeySpec

        public OpenSSHPrivateKeySpec​(byte[] encodedKey)
        Accept an encoded key and determine the format.

        The encoded key should be the Base64 decoded blob between the "---BEGIN and ---END" markers. This constructor will endeavour to find the OpenSSH format magic value. If it can not then it will default to ASN.1. It does not attempt to validate the ASN.1

        Example: OpenSSHPrivateKeySpec privSpec = new OpenSSHPrivateKeySpec(rawPriv);

        KeyFactory kpf = KeyFactory.getInstance("RSA", "BC"); PrivateKey prk = kpf.generatePrivate(privSpec);

        OpenSSHPrivateKeySpec rcPrivateSpec = kpf.getKeySpec(prk, OpenSSHPrivateKeySpec.class);

        Parameters:
        encodedKey - The encoded key.
