• signing and sign verifying with ability of key caching, certificate can be included into signature or not; ability to read certificate or it field from signature;
• keys and certificate request generation by calling Admin-PKI (with no replacing 00000001.key for disk carrier medias); installing certificates (with switching to key corresponding to certificate (for disk carrier medias); reading/viewing certificate or certificate request fields; converting old SKZI Crypto-COM 3.0 keys to new SKZI Crypto-COM 3.1 format; password changing.
• Miscellaneous encoding and cryptographic routines, licensing object (based on CPU/BIOS/HDD information reading from hardware, realized on AllLib), AllLib object to work with symmetric algorithms and CRC/hashing using streams/files/string; object to call CryptoAPI/Crypto-PRO or Signal-COM Message-PRO from same methods, signing/signature verifying dialogs etc.

Demo includes a application which can be used as a Log-in dialog which stores encrypted passwords in a file called "password.dat" in an apllication directory.

• Only windows bitmaps (*.bmp) are supported
• Bitmap size is not altered so empty image and image containing data have same size.
• Each LSB bit in the RGB triple of the bitmap contains embedded data so human eye cannot find the difference between empty image and image containing data.
• Data is password protected.
• Long passwords gives better protection of the data.
• Embedding large files allowed via usage of multiple images

Version 3.0 is not compatible with the previous versions of KASteganographyImage.

This unit is a translation of the RSA Data Security, Inc. MD5 Message-Digest Algorithm described in RFC 1321. The unit contains functions to evaluate MD5 hashsum of a string, a file, a stream or any memory buffer, to convert a hashsum evaluation function result into a string of hexadecimal digits and to compare results of two evaluations.

No other files nor dynamic libraries are required to compile and use this unit.

SecureBlackbox is split to several packages:

• PKIBlackbox - offers support for Public Key Infrastructure (X.509 certificates, certificate requests, certificate revokation lists, certificate storages etc.). PKIBlackbox supports Windows Certificates and Windows Certificate Storages. PKIBlackbox lets you manage certificates, stored on CryptoCards and USB CryptoTokens, via CryptoAPI.
• PGPBlackbox - clean-room implementation of all PGP algorithms and standards with support for operations with PGP keys and keyrings
• PDFBlackbox - clean-room implementation of PDF compression, encryption and signing specifications. Public Key (X.509 certificates) and symmetric encryption is supported. PKCS#1 and PKCS#7 signing is supported.
• SSLBlackbox - client and server components that provide complete support for SSL2, SSL3 and TLS1. Unlike other components SSLBlackbox contains original implementation of all encryption algorithms and security protocols, used in the package, and doesn't depend on third-party libraries.
• MIMEBlackbox - high-quality MIME components with own character conversion tables and own MIME parser/assembler. MIMEBlackbox offers support for S/MIME and PGP/MIME too. DomainKeys technology is supported.
• SSHBlackbox - client and server components that provide support for SSH1 and SSH2 (including compression) and don't depend on third-party libraries.
• SFTPBlackbox - client and server components that provide support for Secure File Transfer Protocol (SFTP, SSH-based protocol).
• FTPSBlackbox - client-side component, which implements FTP (RFC 959) and FTP-over-SSL (RFC 2228) protocols for secure file transfer.
• Many more...

Classes are built as new TStream descendant classes and can thus be used wherever normal streams can be used. They wrap around existing classes so that you can use them with whatever TStream descendant classes you might already be used.

StreamSec Tools 2.1 was in some sense was a "too" comprehensive tool set. It contained everything from basic symmetric encryption to complex protocols such as SSL/TLS. Most customers were really only looking for a single security feature, and consequently they (a) paid for features they didn't really need and (b) had a hard time finding their way in the tool set. It also became increasingly hard to extend, since modularity and code size had not been design goals from the start.

For this reason, StreamSec Tools 3.0 is a complete rewrite with a modular architecture that both allows us to sell just parts of it to fit specific customer demands, and allows us to extend it with new features without cluttering the API for every user each time we do so.
