Generating checksums—cryptographic hashes such as MD5 or SHA-256 functions for files is hardly anything new and one of the most efficient means to ascertain the integrity of a file, or to check if two ...

The old and insecure MD5 hashing function hasn’t been used to sign SSL/TLS server certificates in many years, but continues to be used in other parts of encrypted communications protocols, including ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

OpenSSL is a powerful Secure Sockets Layer cryptographic library. Apache uses it for HTTPS encryption, and OpenSSH uses it for SSH encryption. But, you don't have to use it as a library. It's also a ...

The Nokia (previously Alcatel) SR-OS stores some values such as BGP MD5 strings in an obfuscated format in the configs. This is a hassle if you need to confirm a value or move a peering to a different ...
