abapPGP
ABAP implementation of OpenPGP
Requirements
https://github.com/Sumu-Ning/AES
Work in progresss
Current scope is signing, see abapGit/abapGit#358
Warning
It is stupid to write your own encryption/PGP library, abapPGP will most certainly contain severe bugs.
Do not use this for anything important, instead use real PGP software like openPGP
