Description

CryptoPressStream is a streaming compression and encryption library. It provides transparent access to compressed or encrypted data stored in the stream object. All stream objects are 100% compatible with TStream and have some advanced functionality like progress event, LoadFromStream, LoadFromFile, SaveToStream, SaveToFile methods, Lock and Unlock methods for multi-thread usage. CryptoPressStream includes TCPSManager component (thread safe) that provides easiest setting of compression and encryption parameters, contains list of opened streams.

Key features:

• Transparent streaming compression and encryption library with 100 % TStream compatibility.
• Forward and backward seeks to any position, partial rewriting of the stream, read cache.
• Support for large 64-bit streams (> 2 Gb).
• Compression and encryption component supporting buffers, strings, files.
• Compression algorithms ZLIB, BZIP and PPM.
• Strong customizable encryption with binary key support (12 algorithms and 4 modes): Rijndael (AES) 128 and 256, Blowfish, Twofish 128 and 256, DES single, double and tripple, Square.
• TCPSManager component for compression and encryption settings, list of opened stream, memory leaks prevention.
• Native VCL, does not require any DLLs.
• 7 Demos, Component Reference with Delphi and C++ prototypes.
• Royalty free.

Description

DIUcl is the Delphi port of the popular UCL Compression Library, whose lossless algorithm is used by the UPX Ultimate Packer for eXecutables.

DIUcl achieves an excellent compression ratio (up to Zip and BZip) with the following features:

• Decompression is extremely fast, and requires no memory.
• The assembler optimized decompressor fits into less than 200 bytes of code.
• Supports in-place compression and decompression.
• Real-time decompression should be possible for any application.

Description

Easy Compression Library is a very easy-to-use replacement of TFileStream, TMemoryStream and other TStream descendants to their analogues with compression / decompression and encryption. Compression is transparent, all the methods, properties and behavior of TFileStream and TMemoryStream are supported, so it is very simple to replace them in the application code.

Description

The SQX archiver is a high performance file archiver. It was developed because the specifications for most other archivers are not fully available to third parties.

You are allowed to freely use the provided format specifications, the source code, source samples and precompiled DLLs – all without paying any license fees.

The main advantages of SQX format are:

• Main compressor is a LZH variant supporting LZ dictionaries from 32K up to 4096K
• Ultra compression mode with dictionary up to 32768K
• Several compressor extensions to handle multimedia data
• High speed audio (WAV) compressor
• Special compressor stage for IA32 executables
• Solid and non-solid archives support
• Strong 128/256-bit AES encryption (Rijndael) for file data
• Independent encryption of archive directories
• Internal and external data recovery records
• Full support for 64-bit file systems (the size of archives and archive volumes is limited only by the OS)
• Support for digitally signed archives (envelope up to 512 bit, encrypted with 2 * 1024 bit)
• SFX modules for DOS (32bit PMode), Win32 and x64. All SFX modules support multi-volume archives
• Archive and file comments.

Description

TCompress provides native components for the creation of multi-file compressed archives, as well as database, file, resource and in-memory compression using streams. Three compression methods (RLE, LZH1 and and LZH5) are built in, with "hooks" for the easy addition of custom compression formats. Now supports thread-safe operation and .NET.

TCompress also includes drop 'n play components for automatic database blob, image, rich text and memo compression, based on the VCL's TDBMemo, TDBRichText and TDBImage components. Images compress by up to 98% when using LZH, hence there is a massive saving in disk space and disk or network access when using these components.
