3des

Is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block. The Data Encryption Standard's (DES) 56-bit key is no longer considered adequate in the face of modern cryptanalytic techniques and supercomputing power.

aes

Is a specification for the encryption of electronic data established by the U.S National Institute of Standards and Technology (NIST) in 2001. AES is widely used today as it is a much stronger than DES and 3DES despite being harder to implement.

caesar

This method requires two inputs one a number and a plaintext. The Time Complexity and Space Complexity both are O(N). The encryption formula is En(x) = (x + n) mod 26 and the Decryption formula is Dn(x) = (x – n) mod 26. Made in: Java Netbeans 8.2

des

The DES is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography.

digital-signature

RSA is a widely used algorithm for digital signatures because it provides strong security and efficient performance. Digital signatures are used to verify the authenticity of digital documents and ensure that they have not been tampered with.

hash-number

The program could have a simple user interface that allows the user to select a file from their file system. Once the user selects the file, the program calculates the hash of the file's content and displays this value to the user.

polybius

The Polybius square or Polybius checkerboard is a method for fractionating plaintext characters so that they can be represented by a smaller set of symbols.

rc4

The RC4 (Rivest Cipher 4) encryption algorithm is a symmetric key encryption algorithm that encrypts plain text in small chunks producing multiple stream cipher.

rsa

Is the most widely used asymmetric cryptography algorithm. Based on mathematical and arithmetic principles of prime numbers, it uses large numbers, a public key and a private key, to secure data exchanges on the Internet.

rsa-generator

This tool generate RSA public key as well as the private key.

scytale

Method of encrypting consisted of a tapered baton around which was spirally wrapped a piece of parchment inscribed with the message. When unwrapped the parchment bore an incomprehensible set of letters, but when wrapped around another baton of identical proportions, the original text reappeared.

vigenere

Method of encrypting alphabetic text by using a series of interwoven Caesar ciphers based on the letters of a keyword. Though the 'chiffre indéchiffrable' is easy to understand and implement, for three centuries it resisted all attempts to break it.
