Shamir's secret sharing (SSS) is an efficient secret sharing algorithm for distributing private information (the "secret") among a group. The secret cannot be revealed unless a quorum of the group acts together to pool their knowledge. To achieve this, the secret is mathematically divided into parts (the "shares") from which the secret can be ...
An example paper printable bitcoin wallet consisting of one bitcoin address for receiving and the corresponding private key for spending. A cryptocurrency wallet is a device, [1] physical medium, [2] program or an online service which stores the public and/or private keys [3] for cryptocurrency transactions.
For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format. 416 Range Not Satisfiable The client has asked for a portion of the file (byte serving), but the server cannot supply that portion. For example, if the client asked for a part of the file that lies beyond the end of the file.
In cryptography, a shared secret is a piece of data, known only to the parties involved, in a secure communication. This usually refers to the key of a symmetric cryptosystem . The shared secret can be a PIN code , a password , a passphrase , a big number, or an array of randomly chosen bytes.
For example, a journalist can publish the public key of an encryption key pair on a web site so that sources can send secret messages to the news organization in ciphertext. Only the journalist who knows the corresponding private key can decrypt the ciphertexts to obtain the sources' messages—an eavesdropper reading email on its way to the ...
Static KBA, also referred to as "shared secrets" or "shared secret questions," is commonly used by banks, financial services companies and e-mail providers to prove the identity of the customer before allowing account access or, as a fall-back, if the user forgets their password. At the point of initial contact with a customer, a business using ...

Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
