secure hash algorithm การใช้

• SHA-3 is a member of the Secure Hash Algorithm family.
• It would be better to choose a more secure hash algorithm ( see notes below ).
• "' SHA-2 "'( Secure Hash Algorithm 2 ) is a set of cryptographic hash functions designed by the National Security Agency ( NSA ).
• Dash uses a chained hashing algorithm called X11 for the SHA-256 ( from well-known Secure Hash Algorithm family ) or scrypt it uses 11 rounds of different hashing functions.
• SHA-1 and SHA-2 are the secure hash algorithms required by law for use in certain U . S . Government applications, including use within other cryptographic algorithms and protocols, for the protection of sensitive unclassified information.
• Secret material can be sent within the U . S . via registered mail, and Confidential material by Secure Hash Algorithm ( SHA ), Elliptic Curve Digital Signature Algorithm ( ECDSA ) and Elliptic curve Diffie Hellman ( ECDH ).
• The current version of the SHS standard is the document NIST FIPS 180-4, which specifies seven Secure Hash Algorithms : SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512 / 224 and SHA-512 / 256.
• In cryptography, "'SHA-1 "'( "'Secure Hash Algorithm 1 "') is a cryptographic hash function designed by the United States National Security Agency and is a U . S . Federal Information Processing Standard published by the United States NIST . SHA-1 produces a 160-bit ( 20-byte ) hash value known as a message digest.
• Based on the resulting algorithms, the design requirements appear to be ( 1 ) confidentiality, ( 2 ) integrity protection ( authentication ), ( 3 ) efficiency, ( 4 ) use of standard ( approved ) underlying primitives such as the Advanced Encryption Standard ( AES ) and the Secure Hash Algorithm ( SHA-1 ), and ( 5 ) consideration of additional circumstances ( e . g ., resilience to operator error, low-quality random number generators ).
