php-gpg
|
||
|
|
=======
|
||
|
|
|
||
|
|
php-gpg is a pure PHP implementation of GPG/PGP (currently supports encryption only). The library does not require PGP/GPG binaries and should run on any platform that supports PHP.
|
||
|
|
|
||
|
|
This library is useful for encrypting data before it is sent over an insecure protocol (for example email). Messages encrypted with this library are compatible and can be decrypted by standard GPG/PGP clients.

I'd like to release this under a more permissive license, but since PGP & GPG itself are GPL, I think this library is likely bound to the terms of GPL as well.
