base全家桶的安装使用方法
base编码是Binary-to-text encoding的一种实现方法,它可以把二进制数据(含不可打印的字符)编码成可打印字符序列。
本文会不定时收录“base全家桶”:base64、base32、base16、base58、base91、base92、base36、base62、base85、base128等。
收录BaseHash(包含base36、base52、base56、base58、base62、base94)
0x01 base64
安装:python2.7自带
alphabet:
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/
padding:
=
使用:
import base64
c=base64.b64encode('pcat.cc')
m=base64.b64decode(c)
print c,m
0x02 base32
安装:python2.7自带
alphabet:
ABCDEFGHIJKLMNOPQRSTUVWXYZ234567
padding:
=
使用:
import base64
c=base64.b32encode('pcat.cc')
m=base64.b32decode(c)
print c,m
0x03 base16
安装:python2.7自带
alphabet:
0123456789ABCDEF
使用:
import base64
c=base64.b16encode('pcat.cc')
m=base64.b16decode(c)
print c,m
注意:
当b16decode的参数含有小写字母时,需要传入第二个参数True
base64.b16decode('706361742e6363',True)
或者使用python2.7的.decode('hex')则无须考虑大小写。
'706361742e6363'.decode('hex')

0x09 base85
base85种类:
- ASCII85 encoding. This is the default. 0x00000000 is compressed to z. Spaces are not compressed.
- Adobe ASCII85 encoding is same as previous except data is enclosed between <~ and ~> .
- ZeroMQ (Z85) encoding. NOTE! Even though specification says input length must be divisible by 4, this is not currently enforced. Spaces and zeroes are not compressed.
- Character set from RFC1924 which is an April fools joke. Spaces and zeroes are not compressed.
(1) github项目
https://github.com/tuupola/base85
安装:
请先安装PHP的Composer,再
composer require tuupola/base85
使用:
(下面代码分别对应上面4种类型)
<?php
require __DIR__ . '/vendor/autoload.php';
use Tuupola\Base85;
$m='pcat.cc';
$ascii85 = new Base85([
"characters" => Base85::ASCII85,
"compress.spaces" => false, "compress.zeroes" => true
]);
print $ascii85->encode($m) . PHP_EOL;
$adobe85 = new Base85([
"characters" => Base85::ASCII85,
"compress.spaces" => false, "compress.zeroes" => true,
"prefix" => "<~", "suffix" => "~>"
]);
print $adobe85->encode($m) . PHP_EOL;
$z85 = new Base85([
"characters" => Base85::Z85,
"compress.spaces" => false, "compress.zeroes" => false
]);
print $z85->encode($m) . PHP_EOL;
$rfc1924 = new Base85([
"characters" => Base85::RFC1924,
"compress.spaces" => false, "compress.zeroes" => false
]);
print $rfc1924->encode($m) . PHP_EOL;
(2) python3中base64模块自带
#!/usr/bin/env python3
import base64
c=base64.a85encode(b'pcat.cc')
m=base64.a85decode(c)
print(c,m)
c=base64.b85encode(b'pcat.cc')
m=base64.b85decode(c)
print(c,m)
注意:
python3中的a85encode和b85encode分别对应上面4种类型的第1和第4种。
0x0a base128
github项目:https://github.com/rpuntaie/base128
安装:
git clone https://github.com/rpuntaie/base128
cd base128
python3 setup.py install
另外需要先安装bitarray(在windows里安装麻烦)
pip install bitarray
alphabet:
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\xb5\xb6\xb7\xbc\xbd\xbe\xc1\xc2\xc3\xc4\xc5\xc6\xc7\xc8\xc9\xca\xcb\xcc\xcd\xce\xcf\xd1\xd2\xd3\xd4\xd5\xd6\xd7\xd8\xd9\xda\xdb\xdc\xdd\xde\xdf\xe1\xe2\xe3\xe4\xe5\xe6\xe7\xe8\xe9\xea\xeb\xec\xed\xee\xef\xf1\xf2\xf3\xf4\xf5\xf6\xf7\xf8\xf9\xfa\xfb\xfc\xfd\xfe\xff
使用:
#!/usr/bin/env python3
import base128
b128=base128.base128(chars=None, chunksize=7)
c=list(b128.encode(b'pcat.cc'))
m=b''.join(b128.decode(c))
print(c,m)
注意:
- chars至少128字节,如果为None,则使用
base128.base128.defaultchars
- chunksize必须是7的倍数,且小于128。
0x0b BaseHash
BaseHash is a small library for creating reversible obfuscated identifier hashes to a given base and length. The project is based on the GO library, PseudoCrypt by Kevin Burns. The library is extendible to use custom alphabets and other bases. github项目:https://github.com/calve/python-basehash
安装:
pip install basehash
alphabet:
BASE36 = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'
BASE52 = '0123456789BCDFGHJKLMNPQRSTVWXYZbcdfghjklmnpqrstvwxyz'
BASE56 = '23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnpqrstuvwxyz'
BASE58 = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'
BASE62 = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
BASE94 = '!"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~'
(跟前面所介绍的相比,base36的alphabet的小写字母变成大写,base62相同。)
使用:
from basehash import *
print base36().decode('PCAT')
print base52().decode('pc4t')
print base56().decode('pcat')
print base58().decode('pcat')
print base62().decode('pcat')
print base94().decode('pcat.cc')
