Sha!

Sha (Ш, ш) is a letter of the Cyrillic alphabet, representing the consonant sound or . It is roughly equivalent to sh in English, ch in French, sch in German, ש in Hebrew, ş in Turkish, or sz in Polish. In most Latin-alphabet Slavic languages (Czech, Slovak, Slovene, Croatian) this sound is written š, and linguists have adopted this symbol to transliterate ш into the Latin alphabet.

The SHA hash functions are five cryptographic hash functions designed by the National Security Agency (NSA) and published by the NIST as a U.S. Federal Information Processing Standard. SHA stands for Secure Hash Algorithm. Hash algorithms compute a fixed-length digital representation (known as a message digest) of an input data sequence (the message) of any length. They are called “secure” when (in the words of the standard), “it is computationally infeasible to: find a message that corresponds to a given message digest, or find two different messages that produce the same message digest. Any change to a message will, with a very high probability, result in a different message digest.”
