Libsodium encryption

**Libsodium**makes symmetric key cryptography (where a single**encryption**/decryption key is shared by both parties involved) simple with the sodium_crypto_secretbox() and sodium_crypto_secretbox_open() functions. The first function is used to encrypt a string message given a random nonce and a specific symmetric key. See Listing 1. Listing 1- mobil bekas berkualitas First, we extract the public key from the key pair and use it to encrypt some data. 32 is a random parameter used by the RSA algorithm to encrypt the data. This step simulates us publishing the
**encryption**key and someone using it to encrypt some data before sending it to us. - Public-key cryptography refers to cryptographic systems that require two different keys, linked together by some one-way mathematical relationship, which depends on the algorithm used. The private key cannot be recovered from the public key.
- When comparing Crypto++ and
**libsodium**you can also consider the following projects: OpenSSL - TLS/SSL and crypto library. Botan - Cryptography Toolkit. mbedTLS - An open source, portable, easy to use, readable and flexible SSL library. Bcrypt - Modern (-ish) password hashing for your software and your servers. **Libsodium****encryption**algorithm questions, C++ OPEN I would like to make a simple program to encrypt and decrypt messages and files, to do this I decided to use the library "**libsodium**" reading a bit the documentation, some questions came to me. (I want to use algorithms with symmetric keys) There are many questions, so have some patience.
