This article explains why encrypting data transmission is essential, and demonstrates three PHP-based methods—using HTTPS, symmetric encryption (e.g., AES), and asymmetric encryption with OpenSSL—to protect communication, along with sample code and key management tips.
This guide shows how to generate a self‑signed SSL certificate for an internal IP address using OpenSSL, configure Nginx to serve HTTPS without security warnings, and import the certificate into Chrome with the necessary extensions to avoid common name errors.
This step‑by‑step guide shows how to upgrade the outdated OpenSSH 7.4p1 and OpenSSL 1.0.2k on a CentOS 7 server by first installing Telnet as a fallback, removing the old packages, installing OpenSSL 1.1.1g, compiling OpenSSH 8.3p1, adjusting the configuration, and finally testing the new SSH service.
This comprehensive guide explains OpenSSL’s role in cryptography, covering symmetric and asymmetric encryption, hashing, key generation, certificate creation, and practical command‑line examples for encrypting files, managing keys, signing data, and configuring TLS servers, empowering readers to master secure communications.
This guide explains common certificate formats (PEM, DER, CRT, CER), shows how to generate a CA key, CSR, and signed certificate with OpenSSL, demonstrates format conversions, and provides commands for inspecting and verifying certificates, all essential for secure operations.
This tutorial explains how to encrypt sensitive data with PHP's OpenSSL functions, decrypt it, and then safely feed the decrypted results to ECharts to render interactive statistical charts, providing complete code examples for each step.
This article explains why encrypting data transmission is essential, then demonstrates how to secure PHP-based communications using HTTPS, symmetric algorithms such as AES, and asymmetric encryption with OpenSSL, including complete code examples and key management tips.
Apple’s recent change to macOS’s cURL implementation, which forces the ‑‑cacert option to use the system trust store instead of a user‑supplied certificate bundle, has been criticised by cURL founder Daniel Stenberg as unreliable and potentially insecure, though Apple says the behaviour is intentional and not a bug.
This article explains how to protect data transmission in PHP applications by employing HTTPS (SSL/TLS), implementing symmetric encryption such as AES, and using asymmetric encryption with OpenSSL, while highlighting key management practices to ensure confidentiality, integrity, and resistance to man‑in‑the‑middle attacks.
This article explains how PHP's built-in encryption functions such as md5, sha1, base64_encode/decode, and openssl_encrypt/decrypt can be used to secure data transmission, provides code examples demonstrating AES‑128‑CBC encryption and decryption, and highlights their role in protecting sensitive information.
This article explains PHP's built‑in encryption functions—including OpenSSL encryption/decryption, hashing, and password handling—shows how to generate keys, encrypt and decrypt data, and provides best‑practice tips for securely protecting sensitive information in PHP applications.
The OpenSSL 3.2 Alpha has been released, adding client‑side QUIC support, TLS certificate compression, deterministic ECDSA, expanded Ed25519/Ed448 capabilities, AES‑GCM‑SIV, Argon2 with thread‑pool, HPKE, raw public‑key TLS, TCP Fast Open, pluggable post‑quantum signatures, Brainpool curves, SM4‑XTS, and optional Windows certificate‑store integration.
This guide explains three ways to generate SSL certificates using OpenSSL, including creating a private key, self‑signed certificate, and CSR‑based signing, and shows how to configure Nginx to enable HTTPS with the generated certificates.
This article explains why PHP7 deprecates the mcrypt extension in favor of OpenSSL, compares DES, 3DES, and AES algorithms, clarifies key length choices, outlines common encryption modes, and provides practical PHP code for encrypting and decrypting data with OpenSSL.
This guide shows how to enable HTTPS on Nginx by either obtaining a free Alibaba Cloud SSL certificate—generating a CSR, submitting it, and configuring the server—or creating a self‑signed OpenSSL certificate with custom SANs, installing it, updating hosts, and verifying the secure connection.
Version 25.1 of Erlang/OTP, the first maintenance patch for OTP 25, introduces production‑ready OpenSSL 3.0 crypto support, fixes a critical CVE‑2022‑37026 SSL/TLS client‑authentication bypass, adjusts engine loading behavior, and includes various minor bug fixes and enhancements.
The article introduces the DBLE distributed middleware, outlines the main updates in version 3.22.07.0—including read‑write splitting local read, OpenSSL support, hint‑based query plan improvements—and provides the complete release notes, bug fixes, acknowledgments, and related learning resources.
This article introduces the SSL protocol, explains why encryption is needed for database communication, and provides step‑by‑step instructions for generating self‑signed certificates with OpenSSL, converting them for Java, and configuring both DBLE server and client to use SSL, including experimental verification of encrypted versus unencrypted connections.
This article explains how to secure cross‑data‑center traffic by applying TLS principles, setting up a private Certificate Authority, generating self‑signed certificates with OpenSSL, configuring mutual TLS (mTLS) on Nginx proxies for both HTTP and TCP streams, and verifying the setup with curl and redis‑cli commands.
This article explains how to secure cross‑data‑center traffic by encrypting it with TLS/mTLS, covering the principles of TLS, certificate authority roles, generating self‑signed certificates with OpenSSL, and configuring Nginx proxies for both HTTP and TCP streams to provide transparent encrypted channels without modifying applications.
