WebAES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST . It has a fixed data block size of 16 bytes. Its keys can be 128, 192, or 256 bits long. AES is very fast and secure, and it is the de facto standard for symmetric encryption. WebMar 11, 2024 · An easy and fairly secure pencil & paper cipher. Caesar- A Caesar cipher lets you add an arbitrary value, shifting each letter forwards or backwards. Traditionally, the offset is 3, making A into D, B into E, etc. Columnar Transposition- Write a message as a long column and then swap around the columns. Read the message going down the …

So step by step. Create file config_ssl_ca.cnf Notice, config file has an option basicConstraints=CA:true which means that this certificate is supposed to be root. This is a good practice, because you create it once and can reuse.
