encrypt
public String encrypt(String toEncrypt,
                      String secretKey)
Description copied from interface: SpincastCryptoUtils
Encrypts a string, using the given secret key and the 
 AES algorithm. 
 

 The generated encrypted payload
 is a string which is also base64 encoded so it can be
 used in urls, emails, etc.
 

 You must use the associated SpincastCryptoUtils.decrypt(String, String) method to decrypt
 the resultind payload. 
 

 IMPORTANT!: For this method to work,
 JCE policy files may  be installed first, security must
 be configured properly, or security policy must be
 disabled using the SpincastCryptoConfig.removeJavaCryptoRestrictionsOnInit()
 configuration.
