The BCArchive software is designed to compress group of files/folders to encrypted archive (i.e. to a single compressed file).

Features of BCArchive 2 :

· Create compressed and encrypted archive file protected by password.
· Create compressed and encrypted archive file encrypted by public key of another user.
· Add a number of passwords to existing archive file.
· Add a number of public keys to existing archive file so that a number of users can decrypt the archive.
· Generate new or use existing secret/public key pairs in PKCS-12/X.509 format.
· Compress and encrypt data to self-extracted executable program. The user can run the program on computer where BCArchive is not installed and get the data extracted.

BCArchive utilizes the following encryption algorithms, standards and specifications:

· Symmetric algorithms: Blowfish, IDEA, Triple-DES and CAST5.
· Secure Hash Algorithms: SHA-1, MD5 and RIPEMD-160.
· Asymmetric (public/secret key pair) algorithms: RSA, ElGamal / Diffie-Hellman.
· Specifications for public/secret key pair format: PKCS #12, X.509.
· PKCS #5 (recommendations for the implementation of password-based cryptography).
· RFC 2440 specifications for session keys encrypted by symmetric or public key encryption algorithms.

Since BCArchive is compatible with many well-known standards and specifications, the software allows using existing public key databases created for years widely in the world, for example, the keys created for the PGP software.
