What is the core path for hashing with EVP API?

What will be an ideal response?


The core path for hashing with EVP API is as follows:
* EVP_get_digestbyname(): Obtain algorithm type by algorithm name. Supported name strings are MD2, MD4, MD5, MDC2, SHA1, DSS1, and RIPEMD. Both SHA1 and DSS1 are implementations of the SHA1 algorithm.
* EVP_DigestInit(, type): Initialize context according to the algorithm type.
* EVP_DigestUpdate(, , ): Adding data for computation from inputValue with length inputLength to the context.
* EVP_DigestFinal(, , ): Create the hash, also called message digest, from the context, output the result to outputValue, and result length to outputLength.
