Method Details

calculate

public String calculate(String input,
 String secretKey,
 String encoding)
                 throws NoSuchAlgorithmException,
InvalidKeyException,
UnsupportedEncodingException

Deprecated.

Calculates HMAC SHA-256 hash for string.

Overrides:

calculate in class AbstractHasher

Parameters:

input - string which is going to be encoded into HMAC SHA-256 format

secretKey - The key used for initialization of the algorithm

encoding - character encoding of the string which is going to be encoded into HMAC SHA-256 format

Returns:

HMAC SHA-256 representation of the input string

Throws:

NoSuchAlgorithmException - if the HMAC SHA-256 algorithm is not available.

UnsupportedEncodingException - if the specified encoding is unavailable.

InvalidKeyException - Only applicable to HMAC encoding types, when a bad key is provided.

Deprecated.

Calculates HMAC SHA-256 hash for string. Secret key that is supplied here is the input itself.

Specified by:

calculate in class AbstractHasher

Parameters:

input - string which is going to be encoded into HMAC SHA-256 format

encoding - character encoding of the string which is going to be encoded into HMAC SHA-256 format

Returns:

HMAC SHA-256 representation of the input string

Throws:

NoSuchAlgorithmException - if the HMAC SHA-256 algorithm is not available.

UnsupportedEncodingException - if the specified encoding is unavailable.

InvalidKeyException - if key is invalid
