I need to encrypt a text file before I send it to Client. They provided me with .asc file. Can I use Crypt.vcx to do that? They used some PGP software earlier to do the same. If I use Crypt.vcx and use the Key, the one they provided to me as .asc file, will it affect them in any way...say the way they need to Decrypt the file.

Thanks
