Basic implementations of well-known cryptographic ciphers and attacks on these ciphers.
Some of the programs that were created for practicals in college
A simple project to allow a user to encrypt a message with different types of simple ciphers.

Classical Encryption/Substitution Cipher Example
Java code to crack words encrypted using the same key by a Vigenère cipher
This is an symmetric encryption algorithm. It is a more glorified version of a substitution cipher. However, some substitutions are added that do not correspond to a letter to try and confuse anyone trying to break the cipher
Encryption and decryption using symmetric-key substitution algorithms implemented as console application
A simple console application implementation of a combined Transposition-Substitution-Transposition cypher. Course task for the Cryptography course (5th semester). Spaghetti Code Warning! :(
Complete implementations of encryption and decryption algorithms including Advanced Encryption Standard (AES), Data Encryption Standard (DES), Row Transposition Cipher and Vigenere Cipher.
A web application that helps encode and decode plain content
In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth.
