![]() Unsigned char * source = reinterpret_cast(&temp_buffer) Unsigned char Base16EncodeNibble( unsigned char value ) This program illustrates how SHA1 hash values in base32 encoded form can be decoded Note that in contrast with Clifford's code above, which, if I'm not mistaken, assumes the "base32hex" alphabet mentioned on RFC 4648, my code assumes the "base32" alphabet ("A-Z" and "2-7"). Here's some C++ code (with some notable Windows/little endian artifacts) that I wrote to do just that, and to verify the results. However, I was presented last week with a need to decode SHA1 hash values represented in base32 into their original byte arrays. In direct answer to the original (and now old) question, I don't know of any common library for encoding byte arrays in base32, or for decoding them again afterward. Std::cout << ii << std::endl // Converted back Std::cout << b32 << std::endl // Converted to b32 Unsigned long u = *(reinterpret_cast)( &i ) Here's an example, not necessarily the most efficient, but simple #include For the reciprocal, you don't need a library for something you can easily implement yourself (not everything is a lego brick). This library is free software you can redistribute it and/or modify it under the same terms as Perl itself.Did you mean "base 10 to base 32", rather than integer to base32? The latter seems more likely and more useful by default standard formatted I/O functions generate base 10 string format when dealing with integers.įor the base 32 to integer conversion the standard library strtol() function will do that. perldoc MIME::Base32Ĭopyright (c) 2003-2010 Daniel Peder.

The following primary functions are provided: decode Now, in accordance with RFC-3548, Section 5, MIME::Base32 uses the encode_base32 and decode_base32 functions by default. If you need to maintain that behavior, please call encode_base32hex or decode_base32hex functions directly. Prior to version 1.0, MIME::Base32 used the base32hex (or ) encoding and decoding methods by default. This module is for encoding/decoding data much the way that MIME::Base64 does.
