GPG (GNU Privacy Guard)
GPG, or GnuPG, is GNU Privacy Guard. GnuPG is a complete and free replacement for PGP.
Gpg4win is an installer package for GPG that adds a graphical shell and plugins for Microsoft Outlook and Windows Explorer.
Because GPG does not use the patented IDEA algorithm, it can be used without any restrictions.
GnuPG is a RFC2440 (OpenPGP Message Format) compliant application.
GPG Encryption Protocol Support
GnuPG supports the ElGamal, DSA, RSA, AES, 3DES, Blowfish, Twofish, CAST5, MD5, SHA-1, RIPE-MD-160 and TIGER algorithms.

- How to Encrypt an entire Disk
Sometimes instead of encrypting a file or a set of files, you want to encrypt an entire file system, partition, or disk. One of the chief advantages of this approach is that, once you have entered your encryption key, the encryption becomes transparent to both you and your applications. When you power off your computer, [...]...
- Cryptographic Algorithms
Symmetric Cryptographic Algorithms DES (Data Encryption Standard) is perhaps the most widely used cryptographic algorithm. DES is based upon IBM’s Lucifer algorithm. The NBS (National Bureau of Standards) and the NSA (National Security Agency) adopted DES as a federal standard in 1977. DES is a symmetric cipher with an effective key length of 56 bits. [...]...
- PGP (Pretty Good Privacy)
PGP (Pretty Good Privacy) is a data encryption and decryption program used in e-mail messaging, encrypting/decrypting texts, files, or even disk partitions, in order to provide security of data. The program was created in 1991, by Phil Zimmerman. Pretty Good Privacy encryption is based on using a serial combination of data compression, hashing, public-key cryptography [...]...
- WEP (Wired Equivalent Privacy)
Wired Equivalent Privacy (WEP) is the encryption algorithm built into the 802.11 (Wi-Fi) standard. WEP encryption uses the RC4 stream cipher with 40 or 104 bit keys and a 24 bit initialization vector. WEP Key Generation Most 802.11 devices allow WEP keys to be entered using an ASCII passphrase or in hexidecimal format. The conversion [...]...
- Diffie-Hellman
Diffie-Hellman is an asymmetric cipher defined in U.S. Patent 4,200,770 in 1977, the same year that IBM’s algorithm was selected as the Data Encryption Standard. The Diffie-Hellman patent expired on 6 September, 1997. The Diffie-Hellman algorithm is named after its creators: Whitfield Diffie and Martin Hellman. ElGamal is a variant of Diffie-Hellman which was invented [...]...






hi . I have a concern. am working in one of the departments of a bank. I suspect that my co workers are viewing my pc / remotely accessing my Pc while am working. a winvnc is installed in my pc. how can i prove that my pc is being remotely accessed by another co worker? thank you. mito
