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.

decrypt

public String decrypt(String encrypted,
 String secretKey)

Description copied from interface: SpincastCryptoUtils

Decrypts a string that was encrypted using SpincastCryptoUtils.encrypt(String, String).

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.

buildKey

protected byte[] buildKey(String original)

hashSecure

public String hashSecure(String toHash,
 String salt)

Description copied from interface: SpincastCryptoUtils

Will hash a string using BCrypt. This is currently a good way to hash passwords so they can be stored in a database.

You can use SpincastCryptoUtils.generateNewHashSecureSalt() to generate a new salt.

Specified by:

hashSecure in interface SpincastCryptoUtils

generateNewHashSecureSalt

public String generateNewHashSecureSalt()

Description copied from interface: SpincastCryptoUtils

Will generate a new secure salt that can be used with SpincastCryptoUtils.hashSecure(String, String).
