Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	CryptoParametersJ8.TYPES short names, exact names @see CryptoParametersJ8.TYPES_IMPL.
static class	CryptoParametersJ8.TYPES_IMPL Implementing classes are either using PBEWith <digest>And<encryption> - the password-based encryption algorithm defined in PKCS #5: PBEWithHmacSHA256AndAES_256/CBC/PKCS5Padding in CryptoParametersJ8.TYPES_IMPL.ALGORITHM_J8_PBE or AES/GCM/NoPadding in CryptoParametersJ8.TYPES_IMPL.ALGORITHM_J8_GCM (Cipher Algorithm Names/Cipher Algorithm Modes/Cipher Algorithm Padding).

Field Summary

Fields

Modifier and Type	Field and Description
static String	CLEAR_CODE_DEFAULT Prefix to decrypted hex hash to get a clue, what to use and what it is; should be always 10 bytes.
static CryptoParametersJ8.TYPES	DEFAULT_TYPE
static List[]	LISTS
static String[]	PROVIDER_TYPES

Method Summary

Modifier and Type	Method and Description
static List<String>	getSupportedAlgos(List<String> algoList, String type, boolean exact) Checks Java provider with type has exact type or contains any of the strings in algoList.
static List<String>	init() initializes supported parameters by filtering CryptoParametersJ8.TYPES against AlgorithmParameters in system supported cipher suites: first by an exact match with type AlgorithmParameters, then by inexact matching.

Method Detail

getSupportedAlgos

static List<String> getSupportedAlgos(List<String> algoList,
                                      String type,
                                      boolean exact)

Checks Java provider with type has exact type or contains any of the strings in algoList.

Types

may be Cipher, AlgorithmParameters, KeyGenerator, Alg, Mac, SecretKeyFactory.

Parameters:

algoList - the types to be checked

type - the type is ignored if not exact, instead uses the two types: "AlgorithmParameters", "Cipher".

exact - if exact does a exact match

Returns:

the matched results as a list or emtpy list

init

static List<String> init()

initializes supported parameters by filtering CryptoParametersJ8.TYPES against AlgorithmParameters in system supported cipher suites: first by an exact match with type AlgorithmParameters, then by inexact matching. getSupportedAlgos(List, String, boolean)

Returns:

list of supported algo short codes, if nothing is found, the list is empty.
