|
|
* This class implements the Secure Hashing Standard as defined
|
|
* in FIPS PUB 180-1 published April 17, 1995.
|
|
*
|
|
* Many of the variable names in the SHA1Context, especially the
|
|
* single character names, were used because those were the names
|
|
* used in the publication.
|
|
*
|
|
* Please read the file sha1.c for more information.
