When working with security-sensitive applications, it's often important to understand how fast different cryptographic algorithms perform on the system. OpenSSL provides a built-in benchmarking utility that allows you to measure...
When dealing with SSL certificates, it's critical to ensure that the private key matches the certificate signing request (CSR). Mismatched keys can lead to issues during the certificate signing process...
Whether you're securing sensitive information for personal or professional use, encryption is an effective way to keep your data safe. One widely used encryption tool is OpenSSL, which allows you...
Ensuring the authenticity and integrity of an SSL certificate is crucial for secure communications. A common practice is to verify the fingerprint of a certificate, which acts as a unique...
Base64 is an encoding and decoding scheme commonly used to convert binary data into a printable ASCII text format and back. This tutorial demonstrates how to perform Base64 encoding and...
Transport Layer Security (TLS) is a protocol for ensuring secure communication over the network. It encrypts data exchanged between a client and a server. Over the years, TLS has evolved...
When managing multiple private and public keys, it can be easy to lose track of which private key belongs to the public key. Verifying the match between a private key...
OpenSSL is crucial for securing web applications by implementing TLS and SSL protocols. One of the essential tasks when managing SSL/TLS is to understand which ciphers are supported by your...
Private keys are a fundamental component of secure communication, playing an important role in encryption and decryption processes. Private keys can come in different formats; two common ones are PKCS#8...
