Cryptime

Despite very minor security issues, this tiny encryption tool effectively secures information using passwords and time-based security. For the most part, Cryptime's simple interface is a snap to operate. You simply browse for files or folders for encryption, though the ability to drag and drop and Windows integration to encrypt/decrypt documents would be beneficial. The application compares to similar tools by using a password to encrypt/decrypt files and folders. Additionally, like a bank vault, Cryptime will unlock your files only at user-set hours. It easily synchronizes with Internet servers to ensure no one tampers with the system clock. The program sets encrypted documents to allow decryption only from its original PC. On the negative side, Cryptime doesn't allow users to select an encryption algorithm. Also, recipients must have the program to decrypt the files. All things said, this user-friendly 50-use trial software is good for corporate environments where system administrators need time-based security.
