key

A block, often used in a series, which projects beyond the edge of the enframement of an opening and is joined with the surrounding masonry. A block handled in such a manner is keyed to the masonry; see quoin.

A type of dataset used for encryption or decryption. In cryptography, a sequence of symbols that controls the operations of encryption and decryption.

Digitally signs and encrypts data for security-enabled users. [Exchange 5.5]

A key uniquely identifies the object within a bucket. Together, a key and a bucket are used to identify an object inside S3.

The string index to a "hash", used to look up the "value" associated with that key.

A value used to control cryptographic operations, such as decryption, encryption, signature generation or signature verification.

1. Information (usually a sequence of random or pseudorandom binary digits) used initially to set up and periodically change the operations performed in crypto-equipment for the purpose of encrypting or decrypting electronic data, for determining electronic counter-countermeasures patterns ( e.g. , frequency hopping or spread spectrum ), or for producing other key. Note: "Key" has replaced the terms "variable," "key(ing) variable," and "cryptovariable." [NIS] 2. Usually a sequence of random or pseudorandom bits used initially to set up and periodically change the operations performed in crypto-equipment for the purpose of encrypting or decrypting electronic signals, or for determining electronic counter-countermeasures patterns( e.g., frequency hopping or spread spectrum), or for producing other key. [INFOSEC-99] 3. A sequence of symbols that controls the operations of encipherment and decipherment [7498-2].
