Method Details



encrypt
String encrypt(String toEncrypt,
 String secretKey)
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 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.

Decrypts a string that was encrypted using 
 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

hashSecure
String hashSecure(String toHash,
 String salt)
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 generateNewHashSecureSalt() to generate a
 new salt.




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




removeCryptographyRestrictions
void removeCryptographyRestrictions()
                             throws RuntimeException
Tries to remove the Java cryptography restrictions.
 


Throws:
an - Exception is the restrictions can't be removed.
RuntimeException





isRestrictedCryptographyJavaVersion
boolean isRestrictedCryptographyJavaVersion()
Is the current Java version cryptography restricted?
