Bouncy Castle Crypto APIs
The Bouncy Castle Crypto APIs consist of the following: * A lightweight cryptography API in Java. * A provider for the JCE and JCA. * A clean room implementation of the JCE 1.2.1. * A library for reading and writing encoded ASN.1 objects. * Generators for Version 1 and Version 3 X.509 certificat...
DES implementation in Java v1.0 (Data Encryption Standard)
The algorithm is designed to encipher and decipher blocks of data consisting of 64 bits under control of a 64-bit key (although the effective key strength is only 56 bits). It takes a 64-bit block of plaintext as input and outputs a 64-bit block of cipher text. Since it always operates on blocks of ...
Digital Envelope v1.0
The objective of this project is to provide the secure communication over the network using both public key and private key cryptosystems. This is double fold encryption technique. This uses DES algorithm to encrypt the message and it uses the RSA algorithm to encrypt the DES key. This techniqu...
JCO Java Cryptography Objects
JCO (Java Cryptographic Objects is a free (open source) cryptographic package that features simplicity over complexity and stiffness over flexibility.
RSA Encryption Algorithm Illustration
is a candidate of Public Key Cryptosystem.As with all public-key cryptography models, the RSA cryptosystem encrypts and decrypts a message using a pair of keys known as public key and private key. Its security is based on the difficulty of factoring large integers. Presently, most implementations of...
RSA implementation in Java v1.0
The RSA (Rivest, Shamir, Adleman) algorithm can be used for both public key encryption and digital signatures. Its security is based on the difficulty of factoring large integers.
