BCArchive is a tools for compressing a group of files or folders to a single encrypted file, there are several option for encrypting data that implemented on BCArchive, such as

• Create password for the ecnrypted files.
• Compressed and encrypted archive file using the public key of another user.
• Add several passwords to an 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 executable program that self-extract the archive file.

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. BCArchive utilizes the following encryption algorithms, standards and specifications:

• Symmetric algorithms: Rijndael (AES), Blowfish-256, Blowfish-448, IDEA, CAST5, GOST 28147-89, Triple DES.
• Secure Hash Algorithms: SHA-256, 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.

What´s New in version 2.02.4:

• Resolved conflict with OpenOffice software.
• Resolved problems with sending archive file or public key by email.
