至少在OpenSSL驅動程序中使用帶SHA1的PBKDF2(這是硬編碼的)。
下面是兩個代碼片斷,它們從給定的純文本,密碼,salt,迭代計數和IV生成相同的輸出。
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:不用於生產代碼中使用這些值。
這是一個Apache項目,所以你可以看看源代碼。 –
因此我們不再詢問開源項目了嗎? ;) 但你說得對,今天我正在研究它,如果我的工作允許,我會嘗試更新文檔。畢竟這是關於OOS的好事。這是我昨天做的最後一件事,因爲文檔缺乏,我認爲我在這裏給它一個鏡頭,也許有人知道它,我們有它在一個可以找到的地方記錄;) – Mene
是的,你可以問關於開源項目。我沒有downvoted或closevoted,所以這是一個非常好的問題,但我沒有答案,沒有時間查看源代碼來提供答案。如果沒有人回答,你會浪費很多時間,所以你可以看看自己。當你解決它時,不要忘記提供你自己的答案。 –
