B4J Question [SOLVED] How to get a simple sha256 of a string?

Solution
SHA-256 is actually a hashing algorithm, not Encryption. I think i have SHA256 method in my Encryption.bas in Web API 2 optional modules. In future I will rename my module as Hashing.
B4X:
Public Sub SHA256 (str As String) As String
Dim data() As Byte
Dim MD As MessageDigest
Dim BC As ByteConverter
data = BC.StringToBytes(str, "UTF8")
data = MD.GetMessageDigest(data, "SHA-256")
Return BC.HexFromBytes(data).ToLowerCase
End Sub

Solution
Which lib in b4j should i reference for this?
Update: Found it:
Base64 and Encryption library
Here's a library that, for the moment, can perform Base64 encoding and decoding and symmetric algorithm encryption and decryption. Tested symmetric algorithms are DES, Triple DES and AES (Rijndael). As the Java encryption rountines are all byte array oriented you will need my ByteConverter...

just a test of possible encryptions
Test Web
B4X:
Log(Encryption("Hello", "MD5"))
Log(Encryption("Hello", "SHA-1"))
Log(Encryption("Hello", "SHA-224"))
Log(Encryption("Hello", "SHA-256"))
Log(Encryption("Hello", "SHA-384"))
Log(Encryption("Hello", "SHA-512"))
B4X:
Public Sub Encryption (Text As String, Algorithm As String) As String
Dim MD As MessageDigest, BC As ByteConverter
Dim Data() As Byte = MD.GetMessageDigest(BC.StringToBytes(Text, "UTF8"), Algorithm)
Return BC.HexFromBytes(Data).ToLowerCase

MD5 Encrypt/Decrypt Online | 10015 Tools
Online MD5 Encrypt/Decrypt is a free tool for encrypting and decrypting MD5 hashes. MD5 encryption function is irreversible, that means there is no direct method for MD5 decryption. Trial & error method is used for MD5 decryption. Millions of trials are made for cracking MD5 hashes.
