Method Detail

isCryptoRestricted

public static Boolean isCryptoRestricted()

Check if cryptographic strength available in this Java Runtime is restricted. Not every Java Platform supports "unlimited strength encryption", so this convenience method provides a way to check if strength of crypto functions (i.e., max key length) is unlimited or restricted in the current Java runtime environment.

Returns:

true if it can be determined that max key lengths are less than unlimited false if key lengths are restricted null if max key length cannot be determined for any known Cipher transformations
