Getting started

To use only the Common Cryptographic functions

import 'package:gainer_crypto/crypto.dart';

To use the Advanced Cryptographic functions

import 'package:gainer_crypto/crypto_advanced.dart';

To use the encryption decryption functions or the key generation

import 'package:gainer_crypto/encrypt_decrypt.dart';

To use all together

import 'package:gainer_crypto/gainer_crypto.dart';

Usage

All functions from this library start with prefix gr. For eg.

grHashString(GRCryptoType type, String input);

Here grHashString is a function name.

All the class names and enum names start with prefix GR. For eg.

GRKey key = grKeyFromUtf8("32 Length Key...");
GRIV iv = grIVFromLength(16);
GRCryptoType hashType = GRCryptoType.md5;
GRCryptoTypeHMAC hmacHashType = GRCryptoTypeHMAC.hmacSHA1;

Here, GRKey and GRIV are classes GRCryptoType and "GRCryptoTypeHMAC" are enums grKeyFromUtf8 and grIVFromLength are functions
