dcrypto

Summary

Wraps the openssl library to enable easy two way encryption.

Example

import dcrypto.evp;

// Create an AES key
auto key = keyFromSecret("ZYXWVUTSRQPONMLKJIHGFEDCBA", "SALT");

// Create an encryptor class based on the key.
auto encryptor = new EVPEncryptor(key);

// An encryptor class can be used to encrypt more than one string.
auto encrypted = encryptor.encrypt("This is a decrypted string");
auto encrypted2 = encryptor.encrypt("This is a second decrypted string");

// Create a decryption class based on the key.
auto decryptor = new EVPDecryptor(key);

assert(decryptor.decrypt(encrypted2) == "This is a second decrypted string");
assert(decryptor.decrypt(encrypted) == "This is a decrypted string");
assert(decryptor.decrypt(encrypted2) == "This is a second decrypted string");

Encrypted Properties

There is a mixin which allows an encrypted string to be added to a structure or class with a properties for automatic encryption and decryption.

If vibe.d is included, the accessor property is automatically ignored when serialized.

struct User {
	string username;
	mixin (encryptedProperty("password", "ABCDEFGHIJKLMNOPQRSTUVWXYZ"));
	mixin (encryptedProperty("creditCard", "ZYXWVUTSRXPONMLKJIHGFEDCBA"));
}

User user;
user.username = "David";
user.password = "SuperSecretPassword";
user.creditCard = "1234 5258 4566 9789";

assert(user.password_encrypted_ != "SuperSecretPassword");
assert(user.password == "SuperSecretPassword");
assert(user.creditCard == "1234 5258 4566 9789");
