本文中的加密，是指人不能直观看出信息的加密
即：肉眼不可见的加密
1. url编码
from urllib.parse import quote, unquote name = "王大锤" # 编码 utf8_name = quote(name) # utf-8 print(utf8_name) # %E7%8E%8B%E5%A4%A7%E9%94%A4 长度是 9 gbk_name = quote(name, encoding="gbk") print(gbk_name) # %CD%F5%B4%F3%B4%B8 长度是 6 # 解码 print(unquote(utf8_name)) print(unquote(gbk_name, encoding="gbk")) # 王大锤
2. Base64编码
可参考：base64编码原理以及python中的base64模块
# base64编码是将二进制字节流编码为可打印的64个字符 # 以6位分割 bit位都是0，base64约定以‘=’代替 # z -> b'eg==' import base64 name = "王大锤" # 编码： 字符串 -> 二进制 -> base64编码 b64_name = base64.b64encode(name.encode()) print(b64_name) # b'546L5aSn6ZSk' # 解码：base64编码 -> 二进制 -> 字符串 print(base64.b64decode(b64_name).decode()) # 王大锤
3. 字符串转换ascii
name = "王大锤" # 编码 ascii_name = list(map(ord, name)) print(ascii_name) # [29579, 22823, 38180] # 解码 print("".join(map(chr, ascii_name))) # 王大锤
4. md5不可逆
解密推荐去cmd5
import hashlib name = "王大锤" # 编码 print(hashlib.md5(name.encode()).hexdigest()) # 59c22c7bb43b8561cfd3b52f507171cb
5. Unicode转中文
name = "王大锤" # 编码 unicode_name = name.encode("unicode_escape") utf8_name = name.encode("utf-8") gbk_name = name.encode("gbk") gbk2312_name = name.encode("gb2312") print(unicode_name) # b'\\u738b\\u5927\\u9524' print(utf8_name) # b'\xe7\x8e\x8b\xe5\xa4\xa7\xe9\x94\xa4' print(gbk_name) # b'\xcd\xf5\xb4\xf3\xb4\xb8' print(gbk2312_name) # b'\xcd\xf5\xb4\xf3\xb4\xb8' # 解码 print(unicode_name.decode()) # \u738b\u5927\u9524 print(unicode_name.decode("unicode_escape")) # 王大锤 print(utf8_name.decode()) # 默认utf-8 # 王大锤 print(gbk_name.decode("gbk")) # 王大锤
