Hi Peter, Fields are meant for the display of text, not binary data. You could 'base64encode' the binary data before you display it.
Oh, and when treating binary data, you should the 'byte' chunk instead of the 'char' chunk. That way when LiveCode goes all-in Unicode, your script will continuye to work.

There are two fields (In and Out) and two buttons (Encrypt and Decrypt). When I encrypt test in the IDE and then paste the encrypted text from the Out field to the In field and then decrypt it, I get the back the original text. But not in an OS X Standalone. From a few experiments, I suspect that the issue is related to displaying the encrypted text, probably an encoding issue. I'm using LiveCode 6.5.2 under OS X 10.7.5 Here is my script: local tData local tDisplay local tPassword local tSalt local tIV on openStack put the sha1Digest of "My Old Password" into tPassword put "12345678" into tSalt put "1234567890123456" in tIV end openStack on encryptMSG put Field "In" into tData encrypt tData using "aes256" with password tPassword and salt tSalt and IV tIV put it into tDisplay delete char 1 to 16 of tDisplay put tDisplay into Field "Out" end encryptMSG on decryptMSG put Field "In" into tData decrypt tData using "aes256" with password tPassword and salt tSalt and IV tIV put it into Field "Out" end decryptMSG When I copy the encrypted text from the OS X standalone into a text editor (or even Mail), it displays differently (hence my suspicion that this is an encoding issue. I appreciate any suggestions as to where I am going wrong.
