I think it depends on how generic you want this support to be. If you had a limited use case you don't have to support CAST5.
In src/openpgp.js we do things like: `new openpgp_packet_encrypteddata().write_packet(openpgp.config.config.encryption_cipher, sessionkey, result);` We default this `openpgp.config.config.encryption_cipher` to 9 which corresponds to AES256. You could override this if you wanted. I think what you're asking though is actually about the Windows PGP key interaction with your PHP library. Unfortunately, I don't know much about the Windows PGP client, but I imagine there is a way to change the configuration options when generating a key. Alternatively you could generate the key with GPG which should provide more flexibility. Does the php author have any suggestions on the key generation you're looking for? Hope this could help.
