Digest Python Sha

SHA-256 is the recommended stronger alternative to SHA-1 .Either by using a dedicated library or implementing the algorithm in your language, show that the SHA-256 digest of the string "Rosetta code" is: 764faf5c61ac315f1497f9dfa542713965b785e5cc2f707d6468d7d1124cdfcf. 764faf5c61ac315f1497f9dfa542713965b785e5cc2f707d6468d7d1124cdfcfThis is a moderately efficient implementation, about 100 MB/s on a 4096 bytes input buffer on a 32 bit system, using the ldc2 compiler. On a more modern CPU (Intel Ivy Bridge) using HyperThreading, handwritten assembly by Intel is about twice faster.
