(Swift 3,4,5...) Duplicate openssl dgst -sha256 -sign private.pem -out sha256.sig in.datDemonstrates how to duplicate this OpenSSL command: openssl dgst -sha256 -sign private.pem -out sha256.sig in.datThe in.dat file can contain text or binary data of any type. The OpenSSL command does the following:
func chilkatTest() { // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. var success: Bool let pkey = CkoPrivateKey()! // Load the private key from an PEM file: success = pkey.loadPemFile("private.pem") if success != true { print("\(pkey.lastErrorText!)") return } // Load the file to be signed. let fac = CkoFileAccess()! var inData: NSData = fac.readEntireFile("in.dat") let rsa = CkoRsa()! // Import the private key into the RSA component: success = rsa.importPrivateKeyObj(pkey) if success != true { print("\(rsa.lastErrorText!)") return } // OpenSSL uses big-endian. rsa.littleEndian = false var sigBytes: NSData = rsa.signBytes(inData, hashAlg: "sha256") if rsa.lastMethodSuccess != true { print("\(rsa.lastErrorText!)") return } // Save the binary signature to a file. success = fac.writeEntireFile("signature.sig", fileData: sigBytes) if success != true { print("\(fac.lastErrorText!)") return } print("Success.") } |
