Detailed Description

Macro Definition Documentation

◆ APR_ENCODE_BASE32HEX

#define APR_ENCODE_BASE32HEX 8

Generate base32hex encoding instead of base32 encoding

◆ APR_ENCODE_BASE64URL

#define APR_ENCODE_BASE64URL (APR_ENCODE_NOPADDING | APR_ENCODE_URL)

Generate RFC7515 BASE64URL

◆ APR_ENCODE_COLON

#define APR_ENCODE_COLON 16

Generate base16 with colons between each token.

◆ APR_ENCODE_LOWER

#define APR_ENCODE_LOWER 32

Generate base16 with lower case characters.

◆ APR_ENCODE_NONE

#define APR_ENCODE_NONE 0

Generate RFC4648 base16/base32/base64.

◆ APR_ENCODE_NOPADDING

#define APR_ENCODE_NOPADDING 2

Omit the padding character (=) while encoding.

◆ APR_ENCODE_RELAXED

#define APR_ENCODE_RELAXED 1

If relaxed, decode up until the first non base16/base32/base64 character.

◆ APR_ENCODE_STRING

#define APR_ENCODE_STRING (-1)

RFC4648 and RFC7515 compliant BASE64, BASE64URL, BASE32, BASE32HEX and BASE16 encode/decode functions.

The following encodings are supported:

Base 64 Encoding

o Use flag APR_ENCODE_NONE o https://tools.ietf.org/html/rfc4648#section-4
Base 64 Encoding with URL and Filename Safe Alphabet

o Use flag APR_ENCODE_URL o https://tools.ietf.org/html/rfc4648#section-5
Base 64 URL Encoding without Padding

o Use flag APR_ENCODE_BASE64URL o https://tools.ietf.org/html/rfc7515#appendix-C
Base 32 Encoding

o Use flag APR_ENCODE_NONE o https://tools.ietf.org/html/rfc4648#section-6
Base 32 Encoding with Extended Hex Alphabet

o Use flag APR_ENCODE_BASE32HEX o https://tools.ietf.org/html/rfc4648#section-7
Base 16 Encoding

o Use flags APR_ENCODE_NONE/APR_ENCODE_COLON o https://tools.ietf.org/html/rfc4648#section-8

If a non valid character of any kind including whitespace is passed to any of the decoder functions, APR_BADCH will be returned. In this case decoding will still take place, but the results can not be trusted.

If APR_ENCODE_RELAXED is passed to the decoder functions, decoding will be attempted up until the first non valid character. If this results in an invalid state in the decoder, such as but not limited to an odd number of base16 characters, APR_BADCH will still be returned.

If APR_ENCODE_RELAXED is not passed to a decoder function, the decoding will be done in constant time regardless of whether the result returns APR_SUCCESS or APR_BADCH.

If the dest parameter is NULL, the maximum theoretical buffer size is returned in the len field, including space for a terminating zero character if the destination is a string. This value can be used to allocate buffers of a suitable safe size.

If the dest parameter is provided, the encoding or decoding will take place, and the actual number of characters written is returned in the len field, ignoring any terminating zero.

Plain strings are not assumed '\0' terminated unless APR_ENCODE_STRING is provided. When passing a string to one of the encode functions, this value can be passed to indicate a string-valued key, and have the length computed automatically.

◆ APR_ENCODE_URL

#define APR_ENCODE_URL 4

Generate RFC4648 Base 64 Encoding with URL and Filename Safe Alphabet
