python--base64--简单的加密和解密

import base64

a = "liming我是中国人"
bytesString = a.encode(encoding="utf-8")  # 转码--字符串转成字节形式的字符串
#b‘liming\xe6\x88\x91\xe6\x98\xaf\xe4\xb8\xad\xe5\x9b\xbd\xe4\xba\xba‘

encodestr = base64.b64encode(bytesString)  #加密
#参数：字节形式的字符串
#b‘bGltaW5n5oiR5piv5Lit5Zu95Lq6‘
x=encodestr.decode()  # 解码--字节形式的字符串转成字符串
# bGltaW5n5oiR5piv5Lit5Zu95Lq6

decodestr = base64.b64decode(encodestr)  #解密
#b‘liming\xe6\x88\x91\xe6\x98\xaf\xe4\xb8\xad\xe5\x9b\xbd\xe4\xba\xba‘

x=decodestr.decode()

print(encodestr,decodestr,x)
