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.

SHA-1 produces a 160-bit (20-byte) hash value. A SHA-1 hash value is typically expressed as a hexadecimal number, 40 digits long. SHA-1 is the most widely used of the existing SHA hash functions, and is employed in several widely used applications and protocols.

This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions. Adler-32 is often mistaken for a CRC, but it is not: it is a checksum. ^ "Hash functions". www.azillionmonkeys.com. Retrieved 2015-06-10. ^ a b "Hash functions". www.cse.yorku.ca.

Bitcoin miner hash SHA256 2^66 per second and 2^83 per day. 160-bit is not secure against the collision attack. First, SHA-256 is significantly faster (usually) than SHA-512, and is strong enough for the vast majority of uses.

Jul 18, 2024 · SHA-1 or Secure Hash Algorithm 1 is a cryptographic algorithm that takes an input and produces a 160-bit (20-byte) hash value. This hash value is known as a message digest. This message digest is usually then rendered as a hexadecimal number which is 40 digits long.

SHA-1 is 160 bits. That translates to 20 bytes = 40 hex characters (2 hex characters per byte)

HAS-160 is a cryptographic hash function designed for use with the Korean KCDSA digital signature algorithm. It is derived from SHA-1 , with assorted changes intended to increase its security. It produces a 160-bit output.

Use the SHA-512 algorithm to generate hashed data. The hashing functions return a 128-bit, 160-bit, 256-bit, or 512-bit hash of the input data, depending on the algorithm selected.

This algorithm generates a 160-bit hash based on the same principles as MD4 and MD5 hash functions. SHA-1 was used in security applications, protocols and in distributed revision control systems. The purpose of use was to identify revisions and to detect data corruption.

I'm trying to find an authoritative source for the HMAC Key sizes for each of the hashing algorithms below. Specifically for TLS implementations of HMAC. I found this table in RFC5246: Which lets me populate this information: But I am unable to find definitive key sizes for SHA224, SHA384, and SHA512. The HMAC RFC (2104) lists this:
