NtlmAuth
public NtlmAuth()
answerNtChallenge
public static final byte[] answerNtChallenge(java.lang.String password,
byte[] nonce)
throws java.io.UnsupportedEncodingException
answerLmChallenge
public static final byte[] answerLmChallenge(java.lang.String pwd,
byte[] nonce)
throws java.io.UnsupportedEncodingException
encryptNonce
private static byte[] encryptNonce(byte[] key,
byte[] nonce)
convertPassword
private static final byte[] convertPassword(java.lang.String password)
throws java.io.UnsupportedEncodingException
- Used by answerNtlmChallenge. We need the password converted to caps,
narrowed and padded/truncated to 14 chars...
makeDESkey
private static final byte[] makeDESkey(byte[] buf,
int off)
- Turns a 7-byte DES key into an 8-byte one by adding parity bits. All
implementations of DES seem to want an 8-byte key.
