Features:

• ECB, CBC, CFB and OFB modes of operation
• Automatically handles all padding of the input
• High-level functions for encrypting strings, files, buffers and streams
• Additional mode for producing CBC-MACs (keyed hashes)
• Also includes support for base64 encoding and decoding strings
• Full native Delphi source code included in Corporate version.

Features:

• Supports 512, 1024 and 2048 bit keys
• Compatibility to standard RSA keys (example program here)
• Fast implementation
• Performs Key Generation, Encryption, Decryption, Signing and verification
• Built in interface for linking with symmetric algorithms
• Easy to use interface.

ATE allows programmers to provide transparent file encryption on end-users systems.

ATE supports 27 encryption algorithms and 5 encryption modes, including, but not limited to, Blowfish, Rijndael (AES), Twofish and GOST.

ATE can allow access to the data to specific users only, or even by time of the day.

In a hexadecimal editor you can change important text (program name, author, etc) of an executable. Encrypt can give more protection against unautorised changes in the text of an executable. First encode the text in the demonstration program and copy the decoded text to your program. The text will be decoded at runtime by the Encrypt component.

• Native Delphi code.

These sources provide a Delphi (2-8 and 2005-2010) direct interface to PGP requiring a preceding (.) full installation of PGP 6.5.x, 7.x, 8.x, 9.x or 10.x.

Available capabilities:

• Encoding and decoding (encryption/decryption/signing/verifying)
• Creating and verifying file detached (Open)PGP signatures
• Importing, exporting, revoking, deleting keys & certificates
• Several key & certificate management functions
• Key & certificate generation (DH/DSS, RSA)
• x.509 certificate & S/MIME support
• Keyserver functions
• Some utilities

New in Version 5.0.0:

This one is almost exclusively about migration to Unicode based versions of Delphi (2009 and later) with the main issue being the lack of a backwards compatible TStringList type: Hence there's now a new unit called PGPStringList.pas implementing a TRawByteStrings list type capable of dealing with AnsiString and RawByteString types. For keeping compatibility with prior versions of Delphi these types are either an alias or a redefinition of predefined types, please make sure to read the respective help file page. Other changes:

• StrTools.pas has been renamed to PGPStrTools.pas.
• The certificate selection dialog now selects and closes on double clicks.
• The CPP-Builder files have been updated for including the x509 components and working with CPPB 6.

Features:

• 160 bit keylength - roughly equivalent to 1024 bit RSA
• Very fast
• Performs Encryption, Decryption, Signing and verification
• Performs key generation for symmetric encryption
• Full native Delphi source code included in Corporate version.

Threefish is unusual because it does not follow the normal structure of a block cipher, as it has no S-boxes, instead using only additions, rotations, and exclusive-or operations. Optimized for AMD64 systems.
