OpenSSL: Secure Communication Toolkit

Open-source encryption toolkit for secure communication over computer networks, implementing SSL/TLS and general encryption methods like hashing and digital certificates.

What is OpenSSL?

OpenSSL is an open-source encryption toolkit for securing communications over computer networks. It implements Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols as well as general-purpose cryptography functions.

OpenSSL provides tools for data encryption, certificates management, and authentication that allows applications to communicate privately and securely over the Internet. It supports a wide range of encryption algorithms including AES, RSA, SHA-2 for secure communications between a client and a server.

Some of the key features of OpenSSL include:

  • Implementation of SSL and TLS protocols for secure transfer of data over networks
  • Cryptographic libraries for hashing, encryption/decryption, certificates management
  • Command line tools like openssl, ca, req, x509 for certificates generation
  • APIs for use in custom applications requiring encryption capabilities
  • Support for public key infrastructure (PKI) and X.509 digital certificates

As an open-source tool, OpenSSL is used widely on the internet by major web servers and client applications to enable HTTPS and other secure communications. It provides the underlying encryption technologies for online transactions, web browsing, and system administration tasks.
