(Unicode C) Load an Ed25519 Private Key from HexDemonstrates how to load an Ed25519 private key from raw hex bytes. Note: This example requires Chilkat v9.5.0.83 or greater.
#include <C_CkPrivateKeyW.h> #include <C_CkStringBuilderW.h> void ChilkatSample(void) { HCkPrivateKeyW privKey; const wchar_t *privKeyHex; const wchar_t *pubKeyHex; BOOL success; HCkPrivateKeyW privKey2; HCkStringBuilderW sbPubKeyHex; // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. privKey = CkPrivateKeyW_Create(); // We have the hexidecimal encoded bytes of the private key and public key: privKeyHex = L"d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842"; pubKeyHex = L"19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1"; // Load these values into the Chilkat private key object: success = CkPrivateKeyW_LoadEd25519(privKey,privKeyHex,pubKeyHex); if (success == FALSE) { wprintf(L"%s\n",CkPrivateKeyW_lastErrorText(privKey)); CkPrivateKeyW_Dispose(privKey); return; } // --------------------------------------------------------------- // We don't actually need the public key. If we pass an empty string for the public key, // Chilkat will automatically compute it. privKey2 = CkPrivateKeyW_Create(); success = CkPrivateKeyW_LoadEd25519(privKey2,privKeyHex,L""); // Let's get the public key to see that it computed the same value. sbPubKeyHex = CkStringBuilderW_Create(); privKeyHex = CkPrivateKeyW_getRawHex(privKey2,sbPubKeyHex); wprintf(L"computed public key = %s\n",CkStringBuilderW_getAsString(sbPubKeyHex)); // The output should be: // computed public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1 CkPrivateKeyW_Dispose(privKey); CkPrivateKeyW_Dispose(privKey2); CkStringBuilderW_Dispose(sbPubKeyHex); } |
