NE_STRHASH(3) neon API reference NE_STRHASH(3) 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 ter- minator. 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 cre- ated. 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 avail- ability at runtime, e.g. due to FIPS mode. HISTORY ne_strhash and ne_vstrhash is available in neon 0.32.0 and later.
