Encrypting small amounts of data like a 2k whats-app message but something more like 100k needed for the html on a web-page. Yet it makes little sense to trust a subject to modify.

Even though it is not secure, the simple alphabet shifting.

Crypto Secretbox Libsodium

By making the implementation more complex (some memcpys and special casing of short messages), as libsodium has done for its crypto_secretbox_easy[1], you can avoid the need for this padding. This turned out to be pretty hard: the nacl “do” script synthesizes different versions of the same header file for each algorithm, and deletes many of them just after compilation.  so well done david, for putting together such a stimulating and much needed piece of work.

He's been a web developer for 10 years until javascript drove him away. Another permutation is to then compute a hash over the ciphertext and possibly sign that as well. What is the difference with the secretbox package.

Cryptography helps by binding the data to its originator. Feel free to contact me if you have questions and comments.
