Method Detail

bytesToBase64

public static String bytesToBase64(byte[] bytes)

Transforms the input byte array to Base64.

This is intended as an input to hash(String, String, Function), as the encoder.

Parameters:

bytes - The input bytes

Returns:

A base64 string

bytesToHex

public static String bytesToHex(byte[] bytes)

Transforms the given byte array to hexadecimal.

This is intended as an input to hash(String, String, Function), as the encoder.

Parameters:

bytes - The input byte array

Returns:

The output as a hexadecimal string

hash

public static String hash(String hashFunction,
                          String input)
                   throws sailpoint.tools.GeneralException

Performs a hash of the given input with the given hash function.

This implementation takes care of the javax.crypto initialization for you.

Parameters:

hashFunction - The hash function to use

input - The input string to hash

Returns:

The hashed value as a hexadecimal string

Throws:

sailpoint.tools.GeneralException - if any cryptographic failures occur

hash

public static String hash(String hashFunction,
                          String input,
                          Function<byte[],String> encoder)
                   throws sailpoint.tools.GeneralException

Performs a hash of the given input with the given hash function.

This method allows you to replace the encoding implementation if you don’t wish to receive your output as a hexadecimal string.

Parameters:

hashFunction - The hash function to use

input - The input string to hash

encoder - A function to encode the byte array into a String if you wish to replace the hexadecimal implementation

Returns:

The hashed value as a hexadecimal string

Throws:

sailpoint.tools.GeneralException - if any cryptographic failures occur

md5

public static String md5(String input)
                  throws sailpoint.tools.GeneralException

Hashes the input using the MD5 algorithm and returns it as a hex string

Parameters:

input - The input string

Returns:

The MD5 hash of the input string in hex

Throws:

sailpoint.tools.GeneralException - if any cryptographic failures occur

sha256

public static String sha256(String input)
                     throws sailpoint.tools.GeneralException

Hashes the input using the SHA-256 algorithm and returns it as a hex string

Parameters:

input - The input string

Returns:

The SHA-256 hash of the input string in hex

Throws:

sailpoint.tools.GeneralException - if any cryptographic failures occur
