用於加密相關的操作,3.x裡取代了md5模組和sha模組,主要提供 SHA1, SHA224, SHA256, SHA384, SHA512 ,MD5 演算法
import hashlib m = hashlib.md5() m.update(b"hello") print(m.hexdigest()) m.update(b"It's me") print(m.hexdigest()) m.update(b"It's been a long time since we spoken.") print(m.hexdigest()) m2 = hashlib.md5() m2.update(b"helloIt's me") print(m2.hexdigest()) # 输出 5d41402abc4b2a76b9719d911017c592 64f69d95135bc13d4827f871b37f780f 0c9a83e10aa2f9e9629be61146db9cc2 64f69d95135bc13d4827f871b37f780f #第二个和第四个 md5值是相同的,所以第二个加密的是 helloIt'sme
