Function eosio_cdt_sys::assert_recover_key

pub unsafe extern "C" fn assert_recover_key(
    digest: *const capi_checksum256, 
    sig: *const c_char, 
    siglen: usize, 
    pub_: *const c_char, 
    publen: usize
)

Tests a given public key with the generated key from digest and the signature.

@param digest - What the key will be generated from @param sig - Signature @param siglen - Signature length @param pub - Public key @param publen - Public key length

@pre assert recovery key of pub equals the key generated from the digest parameter @post Executes next statement. If was not true, hard return.

Example:

@code checksum digest; char sig; size_t siglen; char pub; size_t publen; assert_recover_key( digest, sig, siglen, pub, publen ) // If the given public key does not match with the generated key from digest and the signature, anything below will never fire. eosio::print("pub key matches the pub key generated from digest"); @endcode
