One-time pad. A format of one-time pad used by the U.S. National Security Agency, code named DIANA. The table on the right is an aid for converting between plaintext and ciphertext using the characters at left as the key. In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single ...
According to Opera Software, it made Opera 10.50 more than seven times faster in SunSpider than Opera 10.10. [ 41 ] [ 42 ] [ 43 ] On 16 December 2010, Opera 11 was released, featuring extensions , [ 44 ] tab stacking (where dragging one tab over another allowed creating a group of tabs), visual mouse gestures and changes to the address bar.

Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5.
It is a set of dynamically linked libraries that provides an abstraction layer which isolates programmers from the code used to encrypt the data. The Crypto API was first introduced in Windows NT 4.0 [1] and enhanced in subsequent versions. CryptoAPI supports both public-key and symmetric key cryptography, though persistent symmetric keys are ...
Blockchain. A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. [1][2][3][4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves).
