| | | | | Digital Signatures The digital signature (sometimes called an electronic signature) isn't a literal digitalized signature. In layman's terms, it is a procedure that guarantees the integrity and the authenticity of digital documents and messages. The name of a digital signature comes from the analogy with the handwritten signature of a paper document. Everyone knows that there is a lot of paperwork in the world of business. And, where there is paperwork, there is a lot of validation, approvals, etc. | |

| | | | | One weird hobby of mine is reasonable properties of cryptographic schemes that nobody promised they do or don't have. Whether that's invisible salamanders or binding through shared secrets, anything that isn't just boring IND-CCA2 or existential unforgeability is just delightful material to construct vulnerabilities with. Normally, with a signature scheme, you have the public key... | |

| | | | | By Tjaden Hess Earlier this week, NIST officially announced three standards specifying FIPS-approved algorithms for post-quantum cryptography. The Stateless Hash-Based Digital Signature Algorithm (SLH-DSA) is one of these standardized algorithms. The Trail of Bits cryptography team has been anticipating this announcement, and we are excited to share an announcement of our own: we built an... | |

| | | These days, there are two major "categories" of encryption. Symmetric key encryption and Asymmetric key encryption. Today we're going to talk about the symmetric side of things. What is it? How does it work? Examples, etc. Let's dive in. What is it? Symmetric encryption is any cipher algorithm where plaintext | ||
