NAME

       ne_strhash, ne_vstrhash - string hash interface

SYNOPSIS

       #include <ne_string.h>

       char *ne_strhash(unsigned int flags, ...);

       char *ne_vstrhash(unsigned int flags, va_list ap);

DESCRIPTION

       The ne_strhash and ne_vstrhash functions can be used to create hashes. The varargs
       argument list must be const char * strings followed by a NULL terminator. The flags
       argument must select exactly one hash algorithm from the list below, which can be
       optionally bitwise-ORed with one of the formatting option. The hash is calculated for the
       concatenation of the argument list, without separators.

   Hash algorithms
       The following hash algorithms are available:

       NE_HASH_MD5
           MD5

       NE_HASH_SHA256
           SHA-256 (SHA-2)

       NE_HASH_SHA512
           SHA-512 (SHA-2)

       NE_HASH_SHA256_256
           SHA-512/256 (SHA-2)

   Formatting options
       By default, the hash is returned as a hexadecimal lower-case character string. The
       following formatting options are available:

       NE_HASH_COLON
           colon-separated hex pairs, e.g.  "aa:11:22..."

       NE_HASH_SPACE
           space-separated hex pairs, e.g.  "aa 11 22..."

RETURN VALUE

       The return value is the ASCII hexadecimal representation of the hash as a
       malloc-allocated, NUL-terminated string, or NULL if the hash cannot be created. The string
       length is determined by the hash algorithm (and formatting options used). Support for hash
       algorithms is specific to the SSL toolkit with which neon is compiled. Some systems will
       further restrict hash availability at runtime, e.g. due to FIPS mode.
