---------- Post updated at 06:37 PM ---------- Previous update was at 03:34 PM ----------

Hi Mirni tahnks fo rthe code. in encryption part it is working fine. a small modification, it should not prompt user to enter the key. is there any other way to encrypt the content without giving key and write output to file.

why im asking is while dycrypting it should not ask me to provide key. im going to sdecrypt the credentials.txt.encrypt file with another script. also can you plz give me code for encrypt and decrypt seperately.
