In cryptography, there are different functions to be performed depending on your use case, and in this article, we will cover encryption vs hashing vs salting and when to use each one. Namely encryption, hashing, and salting. This article will attempt to demonstrate when why and how you should use … [Read more...] about Encryption vs Hashing vs Salting – What is the difference?
DV Certificates – What are Domain Validated SSL Certificates?
Question: What are DV certificates? Answer: Domain Validated (DV) certificates are SSL certificates that undergo validation on the domain and not on the Organization or extended validation. A DV certificate's cryptographic strength and security are generally no different from an OV or EV SSL … [Read more...] about DV Certificates – What are Domain Validated SSL Certificates?
What is a Certificate Signing Request (CSR)?
A Certificate Signing Request (CSR) is the request file to be sent to a Certification Authority (CA) when requesting an SSL certificate. The CSR is created along with the public/private key pair and contains the public key. Examples are provided below on how to generate a CSR, and take note that the … [Read more...] about What is a Certificate Signing Request (CSR)?
Code Signing Certificate – Comparison and Usage
Question: What is a code signing certificate? Answer: A code signing cert is an X509 certificate specifically used to sign code, software, executables, and scripts. Unlike an SSL Certificate used to protect data transmitted to and from a server which also identifies a server, and also unlike a … [Read more...] about Code Signing Certificate – Comparison and Usage
What are SSL certificates? Why you need SSL.
Question: What are SSL certificates? Answer: An SSL certificate is a file containing data about an organization or some entity along with a cryptographically secure public key. The SSL certificate is the centerpiece for providing secure transactions between a client and server by containing the … [Read more...] about What are SSL certificates? Why you need SSL.
OV Certificate – What is an Organization Validated Certificate?
Question: What is an OV certificate? Answer: Organization Validated (OV) certificates are SSL certificates that undergo validation on the Organization rather than the domain. OV is not as extensive as Extended Validation (EV) but is more extensive than Domain Validation (DV). The cryptographic … [Read more...] about OV Certificate – What is an Organization Validated Certificate?
PKCS7 as SignedData, a certificate bundle and OpenSSL
Introduction to PKCS7 What is PKCS7? It is a standard in the "Public Key Cryptography Standards" used as a cryptographic message syntax and as a format for an X.509 certificate and corresponding chain. The bundle or bag does not have to be a full chain and order does not matter as the final chain … [Read more...] about PKCS7 as SignedData, a certificate bundle and OpenSSL
EV Certificates – Extended Validation Certificates
Question: What are EV Certificates? Answer: Extended Validation (EV) Certificates are SSL Certificates that have been issued after a rigorous validation process. The cryptographic strength and security of an EV certificate is no different than that of a DV (Domain Validated) or OV (Organization … [Read more...] about EV Certificates – Extended Validation Certificates
