Thanks for the input.
Actually, i was able to get going by using .bat files to call the pgp command. Instead of trying to use the cd command inside the xp_cmdshell 'cd\ fullpath-to-\pgp.exe --decrypt filename.pgp -o j:\directory-to-put-file-in\'
decryption wound up being something like:
inside x.bat file
cd
pgp.exe '--decrypt "filename.pgp" -o "j:\directory-to-put-file-in\" --passphrase "passphrase"'
encrypt would be
cd
pgp.exe '-er "recipient-enrypted-to" encrypted-filename.csv'
