base58

forked from keis/base58

改变

• 增加了任意数据类型 (建议 bytes 和 str) 的加解密助手函数: b58ec b58dc
• 加密结果为字符串, 第 1 位表示源数据类型:
  • 第 1 位 i 表示源数据为 int 自然数 >=0, 解密后为 int
  • 第 1 位 b 表示源数据为 bytes, 解密后即为 bytes
  • 第 1 位 s 表示源数据为 str 或其他类型, 被 str(data) 的数据, 解密后返回 str
• 加密结果[1:]即为标准 base58
• 示例见: test_b58.py

Base58 and Base58Check implementation compatible with what is used by the bitcoin network. Any other alternative alphabet (like the XRP one) can be used.

Starting from version 2.0.0 python2 is no longer supported the 1.x series will remain supported but no new features will be added.

Command line usage

$ printf "hello world" | base58
StV1DL6CwTryKyV

$ printf "hello world" | base58 -c
3vQB7B6MrGQZaxCuFg4oh

$ printf "3vQB7B6MrGQZaxCuFg4oh" | base58 -dc
hello world

$ printf "4vQB7B6MrGQZaxCuFg4oh" | base58 -dc
Invalid checksum

Module usage

>>> import base58
>>> base58.b58encode(b'hello world')
b'StV1DL6CwTryKyV'
>>> base58.b58decode(b'StV1DL6CwTryKyV')
b'hello world'
>>> base58.b58encode_check(b'hello world')
b'3vQB7B6MrGQZaxCuFg4oh'
>>> base58.b58decode_check(b'3vQB7B6MrGQZaxCuFg4oh')
b'hello world'
>>> base58.b58decode_check(b'4vQB7B6MrGQZaxCuFg4oh')

# Use another alphabet. Here, using the built-in XRP/Ripple alphabet.
# RIPPLE_ALPHABET is provided as an option for compatibility with existing code
# It is recommended to use XRP_ALPHABET instead
>>> base58.b58encode(b'hello world', alphabet=base58.XRP_ALPHABET)
