BCArchive 1.08.8
BCArchive creates encrypted archive and allows you to e-mail it to your friend more>>
to an encrypted archive (i.e. single file).
With BCArchive you may store all you confidential files in archives that will allow you to access them whenever you need. All of your files are being encrypted and therefore protected against unauthorized access.
You may create self-extracted program containing encrypted archive and e-mail it to your friend. He/she will receive this archive and can read your files, either via knowing correct password or via using public/secret key technology.
All already generated public and secret keys used in other programs can be also used in BCArchive to create encrypted archive and e-mail it to desired recipient.
BCArchive uses strong symmetric encryption algorithms such as Blowfish, IDEA, Triple-DES, CAST5; secure hash algorithms: SHA-1, MD5, RIPEMD-160; asymmetric (public/secret key) algorithms such as RSA, ELGamal/Diffie-Hellman; conforms to specifications PKCS #5, PKCS #12, X.509.
BCArchive is convenient software product providing you with strongest encryption technology and ability for efficient management of sensitive data.
Main function of the BCArchive is to provide the user with a tool for compressing and encrypting files and/or folders to a single archive file.
From one hand, BCArchive provides a number of ways to create such an archive file and put sensitive data into it, including Windows shell extension commands and support of drag-and-drop operations. From the other hand, BCArchive utilizes strong and proven encryption algorithms and standards to provide high security level for the data stored inside the compressed files.
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.
Main features:
- 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.
System requirements:
- Minimum 7 MBytes of free HDD space to install and run the BCArchive software.
Version restrictions:
- Compressed and encrypted archive file created by the BCArchive software can store up to 2 Terabytes not compressed data.
- Self-extracted archive file contains all executable code necessary to extract data stored inside the archive. The code includes correspondent symmetric encryption algorithm, public/secret key algorithm, secure hash algorithm implementations as well as the code to uncompress data. Size of the code is about 130 Kbytes, hence minimum size of self-extracted archive is about 130 Kbytes. The limitation does not concern regular (not self-extracted) archive files.

cryptlib 3.1
A security toolkit providing strong encryption and authentication for apps more>>
The library attempts to hide the low-level details of encryption/decryption and authentication from programmers, allowing them to quickly make their projects more secure.
Some of the symmetric encryption (private key) and authentication algorithms that cryptlib supports include the following:
- AES (Rijndael)
- Blowfish
- DES, 3DES
- RC2, RC4, RC5
The following hash algorithms are available in the library:
- MD2, MD4, MD5
- RIPEMD-160
- SHA
It offers services such as:
- S/MIME
- SSL/TLS
- ssh
It features various hashed message authentication code algorithms:
- HMAC-MD5, HMAC-SHA, HMAC-RIPEMD-160
Finally, asymmetric (public/private key) encryption algorithms such as the following are available:
- Diffie-Hellman, DSA, RSA
cryptlib can also be used with a variety of crypto devices (for example, Fortezza cards and Smart cards).
cryptlib contains as core components implementations of the most popular encryption and authentication algorithms, AES, Blowfish, CAST, DES, triple DES, IDEA, RC2, RC4, RC5, and Skipjack conventional encryption, MD2, MD4, MD5, RIPEMD-160 and SHA hash algorithms, HMAC-MD5, HMAC-SHA, and HMAC-RIPEMD-160 MAC algorithms, and Diffie-Hellman, DSA, Elgamal, and RSA public-key encryption.
In addition to these built-in capabilities, cryptlib can make use of the crypto capabilities of a variety of external crypto devices such as hardware security modules (HSMs), Fortezza cards, PKCS #11 devices, and crypto smart cards. The crypto device interface also provides a convenient general-purpose plug-in capability for adding new functionality which will be automatically used by cryptlib.
The library is free if used in personal, freeware, or shareware projects. The library is written in C. ActiveX and C++ wrappers are provided. The project is OSI Certified Open Source Software.
Enhancements:
- The final release contains mostly minor tweaks based on user feedback from the 3.1 final betas, with no noticeable external changes. Internally, the HTTP engine has been significantly improved, TLS 1.1 is now supported (although at release time there were no other known implementations of this to test against), the BeOS port has been re-done to handle the current state of the OS
using GNU development tools instead of the original Be ones (thanks to Simon Taylor for providing access to his system to do the work on), and the perpetual tweaking of the networking subsystem to handle OS-specific quirks has continued.

New stuff, changes and buf fixes in AlphaPeeler Pro. 1.0 beta are:
(1) Professional crypto algorithms are now added.
(2) In classical crypto, user interface is enhanced and file selection and dir. selection common dialogs are added.
(3) In Options Dialog (Freq. Analysis Decryption), User can now select frequency file (*.frq) to set the frequency.
(4) While saving the alphabet frequencies in "statistics" dialog, an extra frequency file (*.frq) is now also saved.
(5) In Caesar cipher encryption dialog, offset is now modulo 26 based, i.e., it keeps circulating no mater how many times user click right shift or left shift.
(6) Useless OK and Cancel buttons in most of the dialogs are now gone for good.
(7) Substitution encryption dialog now also save substitution key file (*.sub) and also user can select *.sub file to set the destination characters.
(8) Technically there was a bug in previous versions of AlphaPeeler, i.e., Substitution decryption algorithm was same as substitution encryption. Now decryption is enhanced by enabling user to select substitution key file (*.sub) and source alphabets are set accordingly.<<less
