RFC 2104
RFC 2104: A Request for Comments (RFC) that specifies the HMAC (Hash-based Message Authentication Code) construction for creating a message authentication code derived from a cryptographic hash function and a secret key. HMAC is widely used for data integrity and authentication, ensuring that messages are not altered or tampered with in transit.
RFC 3161
RFC 3161: This RFC defines a protocol for Internet X.509 Public Key Infrastructure Time-Stamp Protocol (TSP). It provides a means for proving that a set of data existed at a certain point in time and is used in digital signatures, software distribution, and other fields where time-stamping is critical for establishing data integrity and non-repudiation.
RFC 6960
RFC 6960: An RFC that specifies the Online Certificate Status Protocol (OCSP), which is used for obtaining the revocation status of an X.509 digital certificate. OCSP serves as an alternative to certificate revocation lists (CRLs), providing more real-time, on-demand information about whether a certificate is still valid.
Rijndael
Rijndael: The block cipher algorithm that was chosen by the U.S. National Institute of Standards and Technology (NIST) to be the Advanced Encryption Standard (AES). Rijndael was selected due to its robust security, computational efficiency, flexibility, and ease of implementation across a wide range of platforms. It supports a variety of block and key sizes […]
RIPEMD-160 (Race Integrity Primitives Evaluation Message Digest)
RIPEMD-160 (Race Integrity Primitives Evaluation Message Digest): A cryptographic hash function used to generate a unique fixed-size signature for a message or data file. It is used in cybersecurity to verify the integrity of data and detect tampering. Examples include generating a message digest for a software update or a financial transaction.
Reverse engineering
Reverse engineering: The process of analyzing and deconstructing a product or system to understand its design and functionality. It is often used in the software industry to understand how a program or application works and to identify vulnerabilities or potential improvements. Examples include analyzing a competitor’s product to understand its features and capabilities or studying […]
