Constructor Detail

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.

Method Detail

getFormat

public java.lang.String getFormat()

Return the format, either OpenSSH for the OpenSSH propriety format or ASN.1.

Returns:

the format OpenSSH or ASN.1
