(Swift) Get a Certificate's Key SizeDemonstrates how to get the RSA key size of a certificate (for example, 1024-bit, 2048-bit, etc.) Note: This example requires Chilkat v11.0.0 or greater.
func chilkatTest() { var success: Bool = false // For this example, I have a certificate in raw base64 format (not PEM), // that looks like this: "MIIGkDCCBHigAwIBAgIUMDA ... s/iqLsLA==" let sbCertBase64 = CkoStringBuilder()! success = sbCertBase64.loadFile("qa_data/certs/base64Cert.txt", charset: "utf-8") let cert = CkoCert()! success = cert.load(fromBase64: sbCertBase64.getAsString()) if success == false { print("\(cert.lastErrorText!)") return } // Get the public key. let pubKey = CkoPublicKey()! cert.get(pubKey) var numBits: Int = pubKey.keySize.intValue print("Number of bits = \(numBits)") // If using an older version of Chilkat, the key size can be obtained like this: let xml = CkoXml()! xml.load(pubKey.getXml()) let binDat = CkoBinData()! binDat.appendEncoded(xml.getChildContent("Modulus"), encoding: "base64") numBits = 8 * binDat.numBytes.intValue print("Number of bits = \(numBits)") } |
