DIZipWriter is a high performance zipping component with strong AES encryption for Borland Delphi. It creates standard ZIP archives as well as high-security archives with up to 256-bit key size introduced by WinZip 9. There is no other known Delphi component supporting this level of ZIP encryption.

Another unique feature of DIZipWriter is its TStream based interface, which allows to:

  • Create ZIP archives as streams, including files, memory streams, BLOB streams, etc.
  • Create entire ZIP archives in memory or write them directly to database BLOBs.
  • Add ZIP entries from streams using the CopyFrom procedure.
  • Directly stream objects to ZIP archives using the SaveToStream procedure.

In addition to streams, DIZipWriter also works with

  • files, including long file names and relative paths
  • strings
  • memory buffers and records.

For optimal performance, DIZipWriter writes all data straight to the ZIP archive and uses no temporary files. Its footprint and memory requirements and are very small. Includes HTML help and example projects.

FlexCompress is a high-speed compression library developed to provide archive functionality for your applications. This solution provides flexible compression and strong encryption algorithms that allows you to integrate archiving or backup features into your programs in a fast and easy way.

FlexCompress includes our new unique technology, a transaction system. This innovative solution gives you a rapid and simple way of updating archive files providing data integrity like a reliable database system.
Key features:
- Creates archive files of custom format having better compression rate than WinZip and WinRar
- Native VCL; no DLLs; no OCXs
- Adds, moves, extracts, deletes, updates, tests, refreshes a group of files by a single operation
- Creates encrypted archives using strong encryption algorithms
- Creates self-extracting (SFX) archives
- Performs regularly archive updates using transactions that allows canceling all modifications at any time in case of some failures. Also this technology optimizes the speed of the archive modification
- Compresses large files with low memory consumption
- Comprehensive help; lots of demos
- Repairs damaged archives
- Maximum archive size is 2^63 bytes
- Archive splitting and multiple disk spanning support

SLockPK uses the power of public key encryption to protect your software. Recognized by experts as the only secure way to protect software, public key crypto provides a level of security higher than hardware dongles, but using only software.
Features:
  • Public key encryption (RSA) for highest security possible
  • Cryptographic hashing (SHA-1) to lock license to your software
  • Cryptographic hashing (SHA-1) to lock license to a single PC
  • Protects against viruses and cracks
  • Can use optional internet server to make automatic registrations
  • Delivers adverts (so the other 90% of downloads work for you!)
  • Advanced protection against tampering
  • Licenses have an expiry date (software rental or re-registration)
  • Licenses can be created for a single PC or a group of PCs
  • Key generators are impossible
  • Internet server can constantly monitor for cracks
  • Internet server con inform you of downloads and registrations

The UnixCrypt component is the ultra fast crypt implementation for Delphi/BCB. It works exactly as crypt(key, salt) Unix comand (one-way encryption algorithm), which used to encrypt passwords in .htpasswd files in password protected Web directories. [more]
