  - getBitStrength
```
public static int getBitStrength(org.bouncycastle.openpgp.PGPPublicKey key)
                          throws NoSuchAlgorithmException
```
    Utility method to get the bit strength of OpenPGP keys. Bouncycastle is lacking support for some keys (eg. EdDSA, X25519), so this method manually derives the bit strength from the keys curves OID.
    
    Parameters:
    
    key - key
    
    Returns:
    
    bit strength
    
    Throws:
    
    NoSuchAlgorithmException
  - constantTimeAreEqual
```
public static boolean constantTimeAreEqual(char[] expected,
                                           char[] supplied)
```
    A constant time equals comparison - does not terminate early if test will fail. For best results always pass the expected value as the first parameter.
    
    Parameters:
    
    expected - first array
    
    supplied - second array
    
    Returns:
    
    true if arrays equal, false otherwise.
