Há 5 dias · The root of the Merkle tree, called root hash, guarantees the integrity of the whole filesystem and needs to be stored separately. When the root filesystem is mounted, during early userspace, dm-verity takes as input the data disk and root hash and verifies the integrity the filesystem.
Há 2 dias · Towards Federated Key Transparency. In late 2022, I blogged about the work needed to develop a specification for end-to-end encryption for the fediverse. I sketched out some of the key management components on GitHub, and then the public work abruptly stalled. A few of you have wondered what’s the deal with that.

Há 5 dias · A Merkle proof is a method used to verify the presence and integrity of specific data within a dataset using a Merkle tree. It comprises a single data block (leaf), a series of hashes from the tree (branches), and the Merkle root.
Há 2 dias · 2. Introduction. During the transition to post-quantum cryptography, there will be uncertainty as to the strength of cryptographic algorithms; we will no longer fully trust traditional cryptography such as RSA, Diffie-Hellman, DSA and their elliptic curve variants, but we will also not fully trust their post-quantum replacements until they have had sufficient scrutiny and time to discover and ...
Há 4 dias · PrivateKey is an ECDH private key, usually kept secret. These keys can be parsed with crypto/x509.ParsePKCS8PrivateKey and encoded with crypto/x509.MarshalPKCS8PrivateKey. For NIST curves, they then need to be converted with crypto/ecdsa.PrivateKey.ECDH after parsing.
