When handling some high security data like password etc. its always better to use the encryption – decryption methodology. This small example shows this methodology in AX. It uses TextBuffer class of AX To encrypt a string, use the following code: TextBuffer textBuffer = new TextBuffer(); ; textBuffer.setText(_text); textBuffer.encrypt(987654123); // Basic encryption To decrypt a string, use the following code: TextBuffer textBuffer = new TextBuffer(); ; textBuffer.setText(_text); textBuffer.decrypt(987654123); decryptedString = textBuffer.getText(); In these examples, the encryption key is 987654123. This can be any integer.
