$ git clone https://github.com/guyongqiangx/cryptography.git编译, 编译完会自动运行测试。:
$ cd cryptography
cryptography$ cd sha1

cryptography/sha1$测试例子不仅只是测试，还可以当做哈希工具使用:
cryptography/sha1$ ./sha1 -h
Usage:
Common options: [-x|-f file|-s string|-h]
Hash a string:
./sha1 -s string
Hash a file:
./sha1 -f file [-k key]
-x Internal string hash test
-h Display this message计算字符串哈希：
cryptography/sha1$ ./sha1 -s "I like moon!"
./sha1("I like moon!") = 60580c84e774081d149596819fa8a2499c76f5d8
cryptography/sha1$ echo -n "I like moon!" | openssl dgst -sha1
(stdin)= 60580c84e774081d149596819fa8a2499c76f5d8
计算文件哈希:
cryptography/sha1$ ./sha1 -f sha1.o
./sha1(sha1.o) = fb70f3ceef0917427fc6eb795816826756132e15
cryptography/sha1$ openssl dgst -sha1 sha1.o
SHA1(sha1.o)= fb70f3ceef0917427fc6eb795816826756132e15
