![]() ![]() Ignores all characters outside of the encode character-set. PEMĭecoding ignores all white and non-printable characters MIME decoding Īppearance of the padding character in the encoded stream can be avoidedīase64mime and base64pem are the same encodes as base64 but withĮncoded stream line length limit of 76 and 64 characters respectively. BASE64 DECODE LINUX PLUSOf the plus and slash signs it uses minus and underscore. It has an option to convert local native text line breaks into canonicalĬRLF sequences prior to encoding or to convert CRLF sequences into nativeīase64url encoding is technically the same as base64 but instead Uppercase letters, lowercase letters, numbers, plus and slash. This encoding should not be confused with base32.īase64 encoded stream is a multiple of four-character blocks using Base32 decoding is caseīase32hex encoding works the same way as base32 but witn anĪlternative character-set to preserve the encoded data sort order. Padding character at the end of the encoded steam can be avoided byĮncoding data of size divisible by 5. Last encoded block is padded with equal sign end padding. Strings that could be spelled out and typed in by humans. Transport mechanism, including non-case-preserving barcodes or printed out Storage on - or transport over - any medium or data Some letters are skipped intentionally to make this encoding suitable for Decoding is case insensitive.īase32 encoded stream is a multiple of eight-character blocksĬonsisting of letters and numbers. It needs no padding and preserves the sort ![]() ![]() Per RFC 2045 or PEM Printable Encoding per RFC 1421.īase16 encoding produces a multiple of two-character blocks in DESCRIPTION ¶īaseZ encodes/decodes base16, base32, base32hex, base64 orīase64url data stream per RFC 4648 MIME base64 Content-Transfer-Encoding Void base64_decode(string & out, string const& encoded_string) įile base64.Basez - base 16/32/64 encode/decode data to standard output SYNOPSIS ¶īase64pem. ![]() Use this if you know the output should be a valid string Void base64_decode(vector & out, string const& encoded_string) Void base64_encode(string & out, string const& buf) Void base64_encode(string & out, const uint8_t* buf, size_t bufLen) Part of file base64.hpp: void base64_encode(string & out, const vector& buf) It avoids copying the parameters at the expense of a couple of tests.Īdds some handy functions for dealing with strings, although usually the input data is binary and may have zero bytes inside, so typically should not be manipulated as a string (which often implies null-terminated data).Īlso adds some casts to fix compiler warnings (at least on GCC, I haven't run it through MSVC yet). Std::vector decoded = Base64::decode(encoded) Ī bonus here is that the decode function can also decode the URL variant of Base64 encoding. Std::string encoded = Base64::encode(buf, 4) Add the byte to the return value if it isn't part of an '=' character (indicated by 0xff) Size_t encoded_size = encoded_string.size() Make sure string length is a multiple of 4 Expand the return string size to a multiple of 4ī4 = ((b3 & 0x3f) Base64::decode(std::string encoded_string) Calculate how many bytes that needs to be added to get a multiple of 3 Std::string Base64::encode(const BYTE* buf, unsigned int bufLen) Return encode(&buf, (unsigned int)buf.size()) Return "" // Avoid dereferencing buf if it's empty Std::string Base64::encode(const std::vector& buf) Std::string base64_encode(BYTE const* buf, unsigned int bufLen) Std::vector base64_decode(std::string const&) And why have I modified it? Well, because it didn't seem appropriate to me that I should work with binary data stored within std::string object ) Here's my modification of the implementation that was originally written by René Nyffenegger. ![]()
