sm3

Calculate SM3 hash. Codes copied from openssl.

Compile

cd dynamically-linked-openssl # or statically-linked-openssl
cmake .
make

Usage

$ echo -n UMU | openssl SM3
(stdin)= be6be53e426652f41c2a79b9fedc1410602218f43cf0931c57898f36620ff10d

$ echo -n UMU618 | openssl SM3
(stdin)= f39af87a8e70d8257db2a4694fb748e5bc445c3d918c067177fd94f606163f55

$ ./sm3 UMU UMU618
SM3("UMU") = be6be53e426652f41c2a79b9fedc1410602218f43cf0931c57898f36620ff10d
SM3("UMU618") = f39af87a8e70d8257db2a4694fb748e5bc445c3d918c067177fd94f606163f55

Notes

• For statically-linked-openssl, to avoid dependence on dylibs of openssl, I replace OPENSSL_cleanse(p, HASH_CBLOCK); with memset(p, 0, HASH_CBLOCK); in crypto/md32_common.h.

• Only test on macOS Catalina 10.15.2(15C57).
