enum wget_digest_algorithm

Enumeration of different hash digest algorithms.

Enumerator
WGET_DIGTYPE_UNKNOWN | Indicates 'Unknown hash algorithm', returned by wget_hash_get_algorithm()
WGET_DIGTYPE_MD5 | Type 'MD5' digest
WGET_DIGTYPE_SHA1 | Type SHA1 digest
WGET_DIGTYPE_RMD160 | Type RMD160 digest
WGET_DIGTYPE_MD2 | Type 'MD2' digest
WGET_DIGTYPE_SHA256 | Type 'SHA256' digest
WGET_DIGTYPE_SHA384 | Type 'SHA384' digest
WGET_DIGTYPE_SHA512 | Type 'SHA512' digest
WGET_DIGTYPE_SHA224 | Type 'SHA224' digest
WGET_DIGTYPE_MAX | Number of digest types

## Function Documentation

## ◆ wget_hash_printf_hex()

void wget_hash_printf_hex | ( | wget_digest_algorithm | algorithm,
|  | char * | out,
|  | size_t | outsize,
|  | const char * | fmt,
|  |  | ... )

Parameters

  [in] | algorithm | The hash algorithm to use
  [out] | out | Output string buffer
  [in] | outsize | Size of output string buffer
  [in] | fmt | Printf-like format specifier
  [in] | ... | List of arguments

Calculate the hash from the string generated via the printf-style `fmt` and the following arguments and place it as hexadecimal string into `out`.

The ideal length of `out` would be wget_hash_get_len(type) * 2 + 1.
