Node.js 5/6 crypto.createHash BUG

[yi-ge]

Windows and Mac，Node.js v5/v6：

var a = '010203334455667788AF02';

console.log(md5(Buffer(a,'hex').toString('binary'),'hex'));

echo : 9f4eeb2dc8cfc04768149dfb1036009c

Windows and Mac，Node.js v4/0.10.29：

var a = '010203334455667788AF02';

console.log(md5(Buffer(a,'hex').toString('binary'),'hex'));

echo : f4cb7e6847b063001b72646517a9f4c3

crypto.createHash('md5').update(str, 'binary').digest(type || 'binary'); sorry

Yes, the default encoding for digests was changed to utf8 in v5/v6. In v4 and earlier it was binary.

@wy373226722 Why are you converting the input to a “binary” string anyway? MD5 and other hashes convert any input you pass to them to Buffers back anyway.
