Usage

From source file:com.cws.esolutions.security.utils.PasswordUtils.java

/**
 * Provides two-way (reversible) encryption of a provided string. Can be used where reversibility
 * is required but encryption (obfuscation, technically) is required.
 *
 * @param value - The plain text data to encrypt
 * @param salt - The salt value to utilize for the request
 * @param secretInstance - The cryptographic instance to use for the SecretKeyFactory
 * @param iterations - The number of times to loop through the keyspec
 * @param keyBits - The size of the key, in bits
 * @param algorithm - The algorithm to encrypt the data with
 * @param cipherInstance - The cipher instance to utilize
 * @param encoding - The text encoding/*from  w  ww .java 2 s  . c  om*/
 * @return The encrypted string in a reversible format
 * @throws SecurityException {@link java.lang.SecurityException} if an exception occurs during processing
