至少在OpenSSL驱动程序中使用带SHA1的PBKDF2(这是硬编码的)。
下面是两个代码片断,它们从给定的纯文本,密码,salt,迭代计数和IV生成相同的输出。
C/APR(引用功能可以在testcrypto.c找到):
char *plain_text = apr_pstrdup(pool, "some value");
char *passphrase = apr_pstrdup(pool, "some pass");
const int salt_len = 9;
const char salt_in[] = {1, 1, 1, 1, 1, 1, 1, 1, 1};
const int iterations = 1000;
// everything after the 16th byte is ignored for AES 128
const int iv_len = 16;
const char iv_in[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16};
unsigned char *cipher_text = NULL;
apr_size_t cipher_text_len = 0;
apr_size_t block_size = 0;
apr_size_t iv_size = 0;
const apr_crypto_driver_t *driver = get_openssl_driver(r, pool);
apr_crypto_t *f1 = factory(pool, driver);
char *salt = apr_palloc(pool, salt_len);
memcpy(salt, salt_in, salt_len);
apr_crypto_key_t *crypto_key = NULL; // init to NULL is important, see docs!
apr_crypto_passphrase(&crypto_key, &iv_size, passphrase, strlen(passphrase), salt, salt_len, APR_KEY_AES_128, APR_MODE_CBC, 1, iterations, f1, pool);
unsigned char *iv = apr_palloc(pool, iv_len);
memcpy(iv, iv_in, iv_len);
encrypt_block(NULL, pool, driver, f1, crypto_key, plain_text, strlen(plain_text),
&cipher_text, &cipher_text_len, &iv, &block_size, "KEY_AES_128/MODE_CBC");
// Note: b64_len includes spaces for '\0' terminator
int b64_len = apr_base64_encode_len(cipher_text_len);
char *b64 = apr_pcalloc(pool, b64_len);
apr_base64_encode_binary(b64, cipher_text, cipher_text_len);
爪哇:
/* Derive the key, given passphrase and salt. */
final String plainText = "some value";
final String passphrase = "some pass";
final byte[] salt = {1, 1, 1, 1, 1, 1, 1, 1, 1};
final int iterations = 1000;
byte[] iv = new byte[] {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16};
SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
KeySpec keySpec = new PBEKeySpec(passphrase.toCharArray(), salt, iterations, 128);
SecretKey tmp = factory.generateSecret(keySpec);
SecretKey secret = new SecretKeySpec(tmp.getEncoded(), "AES");
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, secret, new IvParameterSpec(iv));
byte[] ciphertext = cipher.doFinal(plainText.getBytes("UTF-8"));
System.out.println(DatatypeConverter.printBase64Binary(ciphertext));
提醒:不用于生产代码中使用这些值。
这是一个Apache项目,所以你可以看看源代码。 –
因此我们不再询问开源项目了吗? ;) 但你说得对,今天我正在研究它,如果我的工作允许,我会尝试更新文档。毕竟这是关于OOS的好事。这是我昨天做的最后一件事,因为文档缺乏,我认为我在这里给它一个镜头,也许有人知道它,我们有它在一个可以找到的地方记录;) – Mene
是的,你可以问关于开源项目。我没有downvoted或closevoted,所以这是一个非常好的问题,但我没有答案,没有时间查看源代码来提供答案。如果没有人回答,你会浪费很多时间,所以你可以看看自己。当你解决它时,不要忘记提供你自己的答案。 –
