3. Generate your RSA key pair using keytool -genkey option. Export your public certificate using -exportcert option. You will need to lookup keytool documentation. Encrypt your name using your private key and encryption mode "RSA/ECB/NoPadding". Submit your certificate and the binary file containing encrypted version of your name. Example to generate a RSA key pair: keytool -genkey-alias cs166-keystore mystore.jks Example to export certificate: keytool -export-alias cs166-keystore mystore.jks -file .cer Example code to Base64 decode a byte array: (JDK1.8) bytel] bt-Files.readAllBytes( "hw4.rsa"); bytel] btDecoded java.util.Base64.getDecoder).decode(bt); Example sample code to get RSA public key from a certificate: static PublicKey getPublicKey0 throws Exception InputStream inStream-new FilelnputStream("s166teacher.cer"); CertificateFactory cf-CertificateFactory.getlnstance("X.509") X509Certificate cert = (X509Certificatelcf.generateCertificate(.nStream); PublicKey pk-cert.getPublicKey); return pk; 3.
