How To Encrypt and Decrypt a File Using OpenSSL

OpenSSL is a robust, commercial-grade, full-featured toolkit for general-purpose cryptography and secure communication. It provides a comprehensive set of cryptographic algorithms, protocols, and libraries that are widely used by software developers and system administrators to implement secure communication and encryption in various applications.

Key Features of OpenSSL:

Secure Socket Layer (SSL) and Transport Layer Security (TLS) Implementation: OpenSSL provides an open-source implementation of the SSL and TLS protocols, which are the de facto standards for secure communication over the Internet. These protocols ensure that data sent over a network is encrypted and protected from eavesdropping and tampering.

Cryptographic Algorithms and Hash Functions: OpenSSL includes a variety of cryptographic algorithms, including RSA, AES, SHA-256, and SHA-512, which are used for encryption, decryption, digital signatures, and secure hashing.
