QuickEncrypt Classic for Mac

From Dejal:

Drop a file on this application to quickly and securely encrypt it, or decrypt previously encrypted files. Supports both QE's original encryption format, and a text-based one, suitable for sending in the body of e-mail messages. Supports self-decrypting archives, so you can send encrypted data to another user without them needing to have QuickEncrypt. QuickEncrypt is very configurable and has many features, including archiving several files in one encrypted file, multiple worksets, user-controlled password limitations, default passwords, automatic encryption and/or decryption, verification of validity, the option of a standard source folder and various destination options, encrypting or decrypting the contents of the Clipboard, and/or saving the encrypted or decrypted data to the Clipboard, opening files once decrypted (via Apple events), and more.
