An example of sha is the letter that came from the Hebrew letter Shin and is similar to the Greek sigma.
sha - Computer Definition
(Secure Hash Algorithm) A family of popular one-way hash algorithms used to create digital signatures. The 160-bit SHA was developed by the National Institute of Standards & Technology (NIST) in 1993, and SHA-1 was the first revision in 1994. SHA-1 is similar to the MD4 and MD5 algorithms developed by Rivest, but is slightly slower and more secure. See MD5. SHA-2 and SHA-3 Released in 2001, the stronger SHA-2 version superseded SHA-1. Because computers are increasingly more powerful, the stronger algorithm is encouraged by certificate authorities (CAs) to prevent an attacker from impersonating a CA. SHA-256 and SHA-512 are SHA-2 algorithms using hash lengths of 256 and 512 bits respectively, and SHA-224 and SHA-384 are truncated versions. SHA-3 was released by NIST in 2015, which supports the same hash lengths as SHA-2 but uses a different cryptographic method based on the Keccak algorithm. SHA-3 was the result of a NIST competition for a new hash standard that began in 2006 and ended in 2012. See one-way hash function and digital signature.
- The "master of the law," as his biographers call him, plunged alone into the terrible desert of the Gobi, then known as the Sha-mo or "Sand River," between Kwa-chow and Igu (now Hami or Kamil).
- In addition to teak, which provides the bulk of the revenue, the most valuable woods are sha or cutch, india rubber, pyingado, or ironwood for railway sleepers, and padauk.
- The chief dyeproduct of Burma is cutch, a brown dye obtained from the wood of the sha tree.
- From such names it is only a step to names of one element, a characteristic feature of which is the frequent addition of an ending -turn (feminine), an, a, um, atum, atija, sha, &c., most of these being " hypocoristic affixes," corresponding in a measure to modern pet-names.
- A state of equilibrium was established, only momentarily disturbed by Kuropatkin's offensive on the Sha-ho in October, and by the Sandepu incident in the winter, until at last Oyama fought a battle on a grand scale and won it.
