Package com.vmware.security.credstore

Class CredentialStoreCipher

  • public class CredentialStoreCipher
extends java.lang.Object
    This class uses the JVM provided classes in javax.crypto.* to encrypt and decrypt text. It uses the RC4 symmetric cipher by default allowing you to store text and decrypt the same text for review later.

    The SecretKey is a vital private key used for encrypting and decrypting the cipher text produced by this class. If you lose the secret key, then the data is lost.

    See Appendix A in the Java Cryptography Extension Reference Guide for more information.

      • ALGORITHM

        public static final java.lang.String ALGORITHM
        The RC4 encryption algorithm is supplied by the JVM. If your JVM does not support RC4 you may have to specify a different algorithm name here.

        See Appendix A in the Java Cryptography Extension Reference Guide for more information.

      • generateSecretKey

        public static javax.crypto.SecretKey generateSecretKey()
                                                throws java.security.NoSuchAlgorithmException
        This helper method will generate a fresh secret key for you to use. If this key is lost, then the information encrypted with this cipher is also lost.
        Returns:
        a key object for use with this class
        Throws:
        java.security.NoSuchAlgorithmException - - thrown if your JVM does not support RC4 encryption
