The BCArchive software is designed to compress a group of files/folders to a single encrypted file. The following options to encrypt data are implemented:

• Create compressed and encrypted archive file protected by password.
• Create compressed and encrypted archive file encrypted using the public key of another user.
• Add several passwords to an existing archive file.
• Apply more than one public keys to an archive file enabling a number of users to decrypt the archive.
• Generate new or use existing secret/public key pairs in PKCS-12/X.509 format.
• Compress and encrypt data to a self-extracted executable program. The user can run the program and extract the data even on a computer where BCArchive is not installed.

BCArchive enables the use of existing public key databases, such as those created for PGP software, which have been used world-wide for many years.
