PGP component and functions

• Uses only pure Delphi code and native PGP SDK dynamic-link libraries. No intermediate or third-party DLLs. Tested on Delphi 7.0, 2005, 2006.
• Shrinks tens of lines of complex code required to perform PGP tasks to a single function call.
• Supports PGP SDK versions 1.7.x and 2.x and requires one of that versions to be installed. See the «Prerequisites» section below.
• All functions are dinamically linked to PGP SDK DLLs so your project will not crash on the client's computer where PGP hadn't yet been installed.
• Default PGP Keyring access (only for version 1.7.x):
  • Retrieve the list of UserIDs from the Default Keyring;
  • Export and Import keys from/to Default Keyring;
  • Validate the secret key's password;
  • Read key info: UserID, Fingerprint (as a string of hex quads), and KeyID;
  • Decode and encode data using UserID: string to string, string to file, file to string, and file to file;
  • Sign messages on encode and retrieve signer(s) info on decode;
• Standalone PGP routines (both SDK versions, does not require using of Keyring files at all):
  • Generate a key pair (secret and public keys);
  • Validate or change the secret key's password;
  • Read key info: User ID, Fingerprint (as a string of hex quads), Secret key (if present), Public key, Key ID, and IsSecretKey flag;
  • Replace all UserIDs existing in the Key by a single UserID. Can be also used to rename an UserID.
  • Decode and encode data using Private or Public Key: string to string, string to file, file to string, memory to memory, memory to file, file to memory, and file to file.
  • Sign messages on encode and retrieve signer(s) info on decode;
  • Create and verify the detached signatures.
• Symmetric cipher (IDEA, 3DES, CAST5) and hash (MD5, SHA, RIPEMD160) components.
