  2. Hash-based cryptography - Wikipedia

    en.wikipedia.org/wiki/Hash-based_cryptography

    The global public key is the single node at the very top of the Merkle tree. Its value is an output of the selected hash function, so a typical public key size is 32 bytes. The validity of this global public key is related to the validity of a given one-time public key using a sequence of tree nodes. This sequence is called the authentication path.

  3. Public-key cryptography - Wikipedia

    en.wikipedia.org/wiki/Public-key_cryptography

    Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.

  4. Merkle signature scheme - Wikipedia

    en.wikipedia.org/wiki/Merkle_signature_scheme

    For each , a hash value of the public key = is computed. Merkle Tree with 8 leaves With these hash values h i {\displaystyle h_{i}} a hash tree is built, by placing these 2 n {\displaystyle 2^{n}} hash values as leaves and recursively hashing to form a binary tree.

  5. Public key fingerprint - Wikipedia

    en.wikipedia.org/wiki/Public_key_fingerprint

    In public-key cryptography, a public key fingerprint is a short sequence of bytes used to identify a longer public key. Fingerprints are created by applying a cryptographic hash function to a public key. Since fingerprints are shorter than the keys they refer to, they can be used to simplify certain key management tasks.

  6. PKCS 1 - Wikipedia

    en.wikipedia.org/wiki/PKCS_1

    In cryptography, PKCS #1 is the first of a family of standards called Public-Key Cryptography Standards (PKCS), published by RSA Laboratories.It provides the basic definitions of and recommendations for implementing the RSA algorithm for public-key cryptography.

  7. HMAC - Wikipedia

    en.wikipedia.org/wiki/HMAC

    HMAC-SHA1 generation. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.

  8. RSA (cryptosystem) - Wikipedia

    en.wikipedia.org/wiki/RSA_(cryptosystem)

    RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission.The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977.

    The HPKP policy specifies hashes of the subject public key info of one of the certificates in the website's authentic X.509 public key certificate chain (and at least one backup key) in pin-sha256 directives, and a period of time during which the user agent shall enforce public key pinning in max-age directive, optional includeSubDomains ...
