DSL_API void DSL_CC | hash_update (HASH_CTX *ctx, const uint8 *input, size_t length) |
| | Call with the data you want to hash, can be called multiple times to hash a large file in chunks for example.

|
DSL_API bool DSL_CC | hash_finish (HASH_CTX *ctx, uint8 *out, size_t outlen) |
| | Finalize hash and store in out. outlen should be >= hashSize in the HASH_CTX struct. After this no further calls to hash_update() can be made and ctx is destroyed.

DSL_API bool DSL_CC | hashdata (const char *name, const uint8 *data, size_t datalen, char *out, size_t outlen, bool raw_output=false) |
| | Wrapper around hash_init()/hash_update()/hash_finish(). If raw_output == true out will contain binary data, otherwise will contain a hex string.

|
DSL_API bool DSL_CC | hashfile (const char *name, const char *fn, char *out, size_t outlen, bool raw_output=false) |

Initialize a hashing CTX with hashing algorithm 'name'
Without optional modules we support: sha3-256, sha3-512, sha256, sha512, sha1, md5, keccak256 (the pre-SHA3 version as used by Ethereum), keccak512
With ENABLE_OPENSSL: Adds the full range of OpenSSL supported hash algorithms
With ENABLE_GNUTLS: Adds RIPEMD-160, MD2, SHA224, SHA384
With ENABLE_SODIUM: Adds blake2b
See hashdata(), hashfile(), hashfile_fp(), and hashfile_rw() for one-shot convenience functions. The hashfile* ones automatically hash the file in 32K chunks so it won't try to load the entire file into memory or anything.
