Free Encryption library for Delphi [closed]

Answer 1

Fundamentals Cody Library has implementations for both AES and RSA encryption. I haven't used the library however so can't comment on it's quality.

Answer 2

TurboPower LockBox 3.1.0 is now released. It supports:

• Delphi 2007 and Delphi 2010
• Unicodestrings for Delphi 2010
• AES, DES, 3DES, Blowfish and Twofish ciphers
• A long list of block chaining modes
• MD5 and SHA1 hashes
• RSA encryption, decryption, signature and verification
• Variable length RSA keys - Almost no contraints on the range.
• D-Unit test code
• Automatic salting
• Proper mangement of IV's (in contrast to DCPcrypt)
• White Box, Free and Open Source
• 100% visible native source code (no DLL's)

Answer 3

Hi Bruce i use this library since Delphi 5,

Delphi Encryption Compedium Part I v.5.2

• Complete Rewrite of the former DEC 3, Update to the DEC 5.1 (released back in 2006)
• Many Ciphers (Blowfish, Twofish, 3DES, Rijndael...)
• Many Hashs (MD2/4/5, SHA1-512, RipeMD128-320...)
• Checksum Functions (CRC32, CRC16...)
• Text conversion Functions (MIME Base 64, XX/UU Coding...)
• Secure Random Number Functions
• with Ciphers encryption in Modes (CTS/CBC/CFB/OFB/ECB...)
• Full and easy object oriented
• Highly optimized, fast core
• Supports ANSI and Unicode in D2009 (and below by using WideStrings)...

Is Freeeware and With Sorce Code, unfortunately does not implement RSA.

Answer 4

I have not tried it in D2010, but DCPcrypt supposedly works in D2009.

Answer 5

• As mentioned by Argalatyr, DCPCrypt works with Delphi 2009 but it doesn't do RSA;

• ChillKat does support RSA and AES for Delphi, but it's not free;

• Sergey Kirichenko made a free Rijndael implementation that you can download here: http://rcolonel.tripod.com/dwnload/rc_rnd.zip. The files are dated november 2000, so I don't know if it'll work directly in the newer Delphi's.

• There used to be a zipfile with Delphi code for download here: http://ace.ulyssis.student.kuleuven.ac.be/~triade/GInt/bin/RSA.zip, but the developer probably finished his study and the university removed his homepage. On this chinese webpage I could see the contents of the file (search for RSA.pas on the page and click the link).

I don't know exactly what you mean with "long in the tooth" (old?), but I'd just go for Lockbox, because it provides everything you need. Except for the 2009 update, the last official changes were made in 2003. But hey, if it works it works.

Answer 6

Looks like the D2010 work is done:

TurboPower LockBox . Data Encryption . Sep 04 2009 . Download

Status: Should be working fine.
This library has been extended so that it supports encryption of Ansi and UnicodeStrings.
09/04/2009
* Delphi 2010 packages
* should compile without hints and warnings
