Openssl evp interface

WebThe EVP interface to digital signatures should almost always be used in preference to the low-level interfaces. This is because the code then becomes transparent to the algorithm used and much more flexible. EVP_DigestVerify() is a one shot operation which verifies a single block of data in one function. WebHeader files and library files of OpenSSL 1.1.1 or higher version are needed while compiling and linking. ... SM2 Encryption and decryption are encapsulated in an abstract level called EVP. In some cases using EVP interfaces to compute SM2 encryption and decryption is a little inconvenient.
