Convert text to UTF-8

Not sure what you are trying to do. Any text in Appian is unicode.

hi rahulb0007  can you post more context on your requirement please

Hi
Stefan Helzle , Abhishek Karumuru , crystalm9043 , thanks for you response.

Java Code:-

byte[] secretString = hmac256((appsecret).getBytes(UTF8), current_time);

What could be equivalent Appian code for above java code snippet? Thanks.

That does not exist in Appian. Appian does not know about bytes etc.

For crypto topics, try one of the available plugins. If none of it does fit your requirements, you will have to develop a plugin yourself.
