Information
DES (data encryption standard) is an encryption algorithm developed in the 1970s which was highly influential; leading to many advancements in cryptography.
However, DES can no longer be considered secure. While no major flaws in its innards are known, it is fundamentally inadequate because its 56-bit (not including 8 parity bits) key is too short.
How to use:
Firstly, input a key. This will be used in the algorithm to encrypt your plaintext. Alternatively, the generate key button will do so for you.
Then, input some plaintext; what you want to encrypt. An output will appear in the bottom boxes with the base64 and hexadecimal versions of your ciphertext along with execution time.
Conversely, to decrypt, simply add the base64 ciphertext into the top input box along with key to decrypt with.
