encrypt

public String encrypt(String toEncrypt,
                      String secretKey)

Description copied from interface: SpincastCryptoUtils

Encrypts a string, using the given secrte 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.
