A cryptographic hash function is a procedure that takes in a variable amount of data and returns a fixed-size bit string known as the data’ signature or hash value. Among the hash functions the most widely used is by far MD5, but currently it’s days are numbered because of breakthroughs in cracking it. One approach I...

XOR Encryption XOR Encryption is a simple symmetric cipher in use in many applications where security is not a defined requirement. Exclusive-OR ( XOR ) encryption is almost unbreakable through brute force methods, although it is susceptible to patterns, it requires that both encryptor and decryptor have access to the encryption...

Introduction As you may have guessed cryptography has been with as for as long as writing itself, the word itself comes from the ancient Greek and has been used for thousands of years to keep military messages secret. One of the first known usage of cryptography is when Julius Caesar sent messages to his generals, because he...
