B4J Question Where can I find the Encryption library?

[MathiasM]

Hello

Where can I find the Encryption library (this one in the docs: https://www.b4x.com/b4j/help/encryption.html)
I only found this one, which is B4A only I think: https://www.b4x.com/android/forum/threads/base64-and-encryption-library.6839/#content

I'm used the search function, but I cannot seem to find it. Any help is appreciated.

B4A encryption library is compatible with B4J.

Ok, in that case I'm doing something wrong..
I have this code for testing:

   Dim testString As String = "test"
   Dim crypto As MessageDigest
   Log(crypto.GetMessageDigest(testString.GetBytes("UTF8"), "SHA-512"))

Error:

B4J line: 36
Log(crypto.GetMessageDigest(testString.GetBytes(\

Any idea?

You cannot log arrays of bytes. GetMessageDigest returns an array of bytes.

If you want to log it:

Dim bc As ByteConverter
Log(bc.HexFromBytes(crypto.GetMessageDigest(...)))

Thanks Erel!

Rookie mistake on my part.
