(Unicode C) Get an Ed25519 Key in Raw Hex FormatDemonstrates how to get the private and public key parts of an Ed25519 key in lowercase hex formmat. Note: This example requires Chilkat v9.5.0.83 or greater.
#include <C_CkPrivateKeyW.h> #include <C_CkStringBuilderW.h> void ChilkatSample(void) { HCkPrivateKeyW privKey; BOOL success; HCkStringBuilderW sbPubKeyHex; const wchar_t *privKeyHex; // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Load an Ed25519 key from some format.. privKey = CkPrivateKeyW_Create(); // This loads an Ed25519 key from an unencrypted PEM file (no password required). success = CkPrivateKeyW_LoadAnyFormatFile(privKey,L"qa_data/eddsa/ed25519.pem",L""); if (success == FALSE) { wprintf(L"%s\n",CkPrivateKeyW_lastErrorText(privKey)); CkPrivateKeyW_Dispose(privKey); return; } // The key type should be "ed25519" to indicate an Ed25519 key. wprintf(L"key type = %s\n",CkPrivateKeyW_keyType(privKey)); // What is the size of the private key in bits? (should always be 256 bits for Ed25519) wprintf(L"size in bits = %d\n",CkPrivateKeyW_getBitLength(privKey)); // Get the private and public key parts in raw hex format: sbPubKeyHex = CkStringBuilderW_Create(); privKeyHex = CkPrivateKeyW_getRawHex(privKey,sbPubKeyHex); // We should have a 32-byte private key (a 64 character hex string). wprintf(L"private key = %s\n",privKeyHex); // We should have a 32-byte public key (a 64 character hex string). wprintf(L"public key = %s\n",CkStringBuilderW_getAsString(sbPubKeyHex)); // Sample output: // key type = ed25519 // size in bits = 256 // private key = d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842 // public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1 CkPrivateKeyW_Dispose(privKey); CkStringBuilderW_Dispose(sbPubKeyHex); } |
