How to send an encrypted file to someone who does not have PGP
Technical Articles ID: SDSKB9
Environment E-Business Server 8.x and 7.x
Summary There are two ways to create an encrypted file, which can be sent to non-PGP users. One can be sent to Windows users. The other can be sent to users on Windows, Unix, and z/OS, but requires that another program be distributed. Both methods involve conventional encryption. Files may be CREATED on Windows, Unix, or z/OS using either method. This article provides examples for the following:
- Create an SDA (Self Decrypting Archive) to send to non-PGP Windows users.
- Create a PGP Archive file to send to non-PGP users on Windows, Unix, and z/OS.
- Create an SDA (Self Decrypting Archive) file:
pgp --encrypt --sda filename --passphrase "passphrase"
- This creates an .EXE (Executable) file that will run on any Windows-based system. NOTE: an SDA may not be larger than 4 GB. If the input file can be compressed, the input file may be larger than 4 GB as long as the resultant SDA is smaller than that.
- Create a PGP Archive (PGA) file:
pgp --encrypt --archive filename --passphrase "passphrase"
- This creates a .PGA (Archive) file that you can use pgpreader to decrypt on a Windows, UNIX, or z/OS system. The pgpreader utility can be found in the E-Business Server program directory and may be freely distributed.
