This validation function tests the C implementation of the SHA1 encryption for the following strings:
"abc""" (an empty string)"abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq""1.23e+4""a" repeated 509 times.If the encrypted strings are identical to the expected (known)
encryption results, the cmpAll boolean variable will
be true.
