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:

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')

0x04 base58

github项目:https://github.com/keis/base58

安装:

alphabet:

123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz

使用:

import base58
c=base58.b58encode('pcat.cc')
m=base58.b58decode(c)
print c,m

0x05 base91

网址:http://base91.sourceforge.net/

github项目:https://github.com/aberaud/base91-python

安装:

alphabet:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!#$%&()*+,./:;<=>?@[]^_`{|}~"

使用:

import base91
c=base91.encode('pcat.cc')
m=base91.decode(c)
print c,m

0x06 base92

github项目:https://github.com/thenoviceoof/base92

安装:

alphabet:

!#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdefghijklmnopqrstuvwxyz{|}

a special denotation (an empty string):

使用:

import base92
c=base92.encode('pcat.cc')
m=base92.decode(c)
print c,m

注意:

encode,b92encode,base92_encode是一样的,
decode,b92decode,base92_decode是一样的。

0x07 base36

github项目:https://github.com/tonyseek/python-base36

安装:

alphabet:

0123456789abcdefghijklmnopqrstuvwxyz

使用:

import base36
c=base36.loads('pcat')
assert type(c)==int
m=base36.dumps(c)
print c,m

注意:

dumps函数接收的参数类型为int

0x08 base62

github项目:https://github.com/suminb/base62

安装:

alphabet:

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

使用:

import base62
m=base62.decode('pcat')
assert type(m)==int
c=base62.encode(m)
print c,m

c=base62.encodebytes('pcat.cc')
m=base62.decodebytes(c)
print c,m

注意:

encode函数接收的参数类型为int

0x09 base85

base85种类:

  1. ASCII85 encoding. This is the default. 0x00000000 is compressed to z. Spaces are not compressed.
  2. Adobe ASCII85 encoding is same as previous except data is enclosed between <~ and ~> .
  3. 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.
  4. 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)

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:

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')
