ACME stands for Automated Certificate Management Environment. It is the protocol that allows web servers to obtain, renew, and revoke TLS certificates automatically, without human intervention. Defined in RFC 8555, ACME was developed by Let’s Encrypt and the IETF to…
Perfect Forward Secrecy (PFS) is a property of a TLS connection that ensures past session traffic cannot be decrypted even if the server’s long-term private key is later compromised. With PFS, each session uses a unique, ephemeral key that is…
Checking if a file has a virus before downloading it is a crucial step in maintaining the security of your computer or device. Here are some methods to help you determine if a file may contain malware: Use Antivirus Software:…
Digitally signing an app is a crucial step in the software development process, especially for ensuring the integrity and authenticity of the app. Here’s a step-by-step guide on how to digitally sign an app: Step 1: Obtain a Code Signing…
A checksum is a value computed from data that lets you detect whether the data has changed. Think of it as a summary that is uniquely sensitive to any modification: if even one character in a file changes, the checksum…
As the frequency and sophistication of cyber threats continue to rise, secure coding practices have become essential for every software development project. The Open Web Application Security Project (OWASP) is a globally recognized authority in the field of application security.…
Your code signing certificate has arrived on a USB hardware token. Since June 2023, this is how every commercially issued OV and EV code signing certificate is delivered (unless you chose a cloud HSM service): the private key is generated…
BYOE stands for Bring Your Own Encryption. It is a cloud security model in which the customer, not the cloud provider, supplies and controls the encryption used to protect their data in the provider’s infrastructure. Instead of relying on the…
A Hardware Security Module (HSM) is a dedicated physical device built for one purpose: generating, storing, and using cryptographic keys in hardware that the keys can never leave. Every cryptographic operation involving a key stored in an HSM happens inside…
This is the complete guide to Public Key Infrastructure (PKI). In this guide you will learn what PKI actually is, the five components that make it work, how a certificate gets issued and verified step by step, and why every…
