powerbuilder 12.1 and pgp

I need to be able to sign a file using pgp within my powerbuilder application

I'm using pb 12.1 classic

Is there an easy way to do this?

I thought about installing gpg4win, and use the command line options

but, that's a little cumbersome

is there an easier way?   I'm seeing some references to the window crypto library

or, the powerbuilder crypto.   Will it do pgp?  or, openpgp

below is my command line option

gpg.exe --armor --batch --yes --passphrase-file " + p_file + " --output " + s_path + '.asc ' + '--local-user ' + key_user + ' --sign ' + s_path
