simple-aes

A simple AES256-ctr based off the node-aes256 package

Example

```rust use simple_aes::{encrypt, decrypt};

fn main() { // Key can be any length since it will be SHA256 hashed let encrypt = encrypt("12345abcdef", "my-super-secret-key").unwrap();

let decrypt = decrypt(encrypt, "my-super-secret-key").unwrap();

assert_eq!(decrypt, "12345abcdef".to_string())

} ```

Flow

• Encryption:
  • Data and key is passed in.
  • Random 16 byte iv is created
  • Key is SHA256 hashed
  • Data is encrypted using the iv and the hash
  • The iv and the encrypted data are concatenated, base64 encoded and returned as a string
• Decryption
  • Key is SHA256 encrypted
  • Encrypted data and key is passed in.
  • Data is base64 decoded to a Vec<u8>.
  • First 16 elements in the Vec are grab for the iv.
  • Every element after the first 16 is passed into decryption along with key
  • The decrypted data is returned as a string
