A cryptographic hash method H (default is SHA-1) A secret key K, which is an arbitrary byte string and must remain private; A counter C, which counts the number of iterations; A HOTP value length d (6–10, default is 6, and 6–8 is recommended) Both parties compute the HOTP value derived from the secret key K and the counter C. Then the ...
Through the collaboration of several OATH members, a TOTP draft was developed in order to create an industry-backed standard. It complements the event-based one-time standard HOTP, and it offers end user organizations and enterprises more choice in selecting technologies that best fit their application requirements and security guidelines.
Version-5 UUIDs are similar, but SHA-1 is used instead of MD5. Since SHA-1 generates 160-bit digests, the digest is truncated to 128 bits before the version and variant bits are replaced. Version-3 and version-5 UUIDs have the property that the same namespace and name will map to the same UUID.
sha1sum can only create checksums of one or multiple files inside a directory, but not of a directory tree, i.e. of subdirectories, sub-subdirectories, etc. and the files they contain. This is possible by using sha1sum in combination with the find command with the -exec option, or by piping the output from find into xargs.
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.
From January 2008 to December 2012, if you bought shares in companies when Howard G. Buffett joined the board, and sold them when he left, you would have a -4.7 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
SHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm . Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010.
The sheriff said Tesla CEO Elon Musk helped the investigation by having the truck unlocked after it auto-locked in the blast and giving investigators video of the suspect at charging stations ...
