When it comes to trustworthy code, small is beautiful. FWIW, RFC-1991 is not a complete specification of PGP-2. You can't implement a compatible version based on this info. You also need to look into the PGP-2 documentation and finally you need to be able to send questions to another person who can provide an answer based on the PGP-2 source code (which is public but due copyright reasons one better does not do it by oneself).

Why would someone want to do that? = The only possible reasons I can think of are: [1] Remailer use, Original remailers used PGP 2.x and even though some use GnuPG, others are reluctant to change anything. [2] Large File Transfers PGP 2.x can be used as a uuencode, and automatically split a signed and encrypted armored file into 100 smaller files ready to be emailed and reconstitued by the receiver. The default for file splitting, is 720 armored lines, but have done it for much more, and successfully sent a 1 gb Truecrypt container and reconstituted it. If you are thinking of looking at PGP 2.x, I would recommend Disastry's version, as it is not limited to MD5 and IDA but can use any HASH and any encryption algorithm except for Camelia. http://www.spywarewarrior.com/uiuc/disastry/263multi.htm (btw, If anyone knows how to install this on 64 bit Ubuntu 14.04 please let me know. It wouldn't compile on Ubuntu 12.x, but was able to install the linux executable PGP on a 32 bit system, but can't on 14.x 64 bit.)

Shalom-Salam, Werner === I'll look into that. We do IP filtering on the firewall so we do know who is getting to our SFTP box (on Aug 3 we will shut down port 21 and standard FTP). All who send data to us must sign a business agreement (HIPAA rules). One such does send us encrypted files that approach 25 GB in size -- yikes!!
