Hashes and hex it with the given String object with the given parameters.

Parameters:

hashIt - the hash it

salt - the salt

hashAlgorithm - the hash algorithm

charset - the charset

Returns:

the generated String object

Throws:

NoSuchAlgorithmException - is thrown if instantiation of the MessageDigest object fails.

UnsupportedEncodingException - is thrown by get the byte array of the private key String object fails.

NoSuchPaddingException - is thrown if instantiation of the cypher object fails.

InvalidKeyException - the invalid key exception is thrown if initialization of the cypher object fails.

BadPaddingException - is thrown if Cipher.doFinal(byte[]) fails.

IllegalBlockSizeException - is thrown if Cipher.doFinal(byte[]) fails.

InvalidAlgorithmParameterException - is thrown if initialization of the cypher object fails.

InvalidKeySpecException - is thrown if generation of the SecretKey object fails.
