/**
* This is an implementation of Sun's proprietary key store algorithm, called "JKS" for "Java Key Store". This
* implementation was created entirely through reverse-engineering.
*
* <p>
* The format of JKS files is, from the start of the file:
*
* <ol>
* <li>Magic bytes. This is a four-byte integer, in big-endian byte order, equal to <code>0xFEEDFEED</code>.</li>
* <li>The version number (probably), as a four-byte integer (all multibyte integral types are in big-endian byte
* order). The current version number (in modern distributions of the JDK) is 2.</li>
* <li>The number of entries in this keystore, as a four-byte integer. Call this value <i>n</i></li>
* <li>Then, <i>n</i> times:
* <ol>
* <li>The entry type, a four-byte int. The value 1 denotes a private key entry, and 2 denotes a trusted certificate.</li>
* <li>The entry's alias, formatted as strings such as those written by <a
* href="http://java.sun.com/j2se/1.4.1/docs/api/java/io/DataOutput.html#writeUTF(java.lang.String)"
* >DataOutput.writeUTF(String)</a>.</li>
* <li>An eight-byte integer, representing the entry's creation date, in milliseconds since the epoch.
*
* <p>
* Then, if the entry is a private key entry:
* <ol>
* <li>The size of the encoded key as a four-byte int, then that number of bytes. The encoded key is the DER encoded
* bytes of the <a
* href="http://java.sun.com/j2se/1.4.1/docs/api/javax/crypto/EncryptedPrivateKeyInfo.html">EncryptedPrivateKeyInfo</a>
* structure (the encryption algorithm is discussed later).</li>
* <li>A four-byte integer, followed by that many encoded certificates, encoded as described in the trusted certificates
* section.</li>
* </ol>
*
* <p>
* Otherwise, the entry is a trusted certificate, which is encoded as the name of the encoding algorithm (e.g. X.509),
* encoded the same way as alias names. Then, a four-byte integer representing the size of the encoded certificate, then
* that many bytes representing the encoded certificate (e.g. the DER bytes in the case of X.509).</li>
* </ol>
* </li>
* <li>Then, the signature.</li>
* </ol>
* </ol> </li> </ol>
*
* <p>
* (See <a href="http://metastatic.org/source/genkey.java">this file</a> for some idea of how I was able to figure out these algorithms)
* </p>
*
* <p>
* Decrypting the key works as follows:
*
* <ol>
* <li>The key length is the length of the ciphertext minus 40. The encrypted key, <code>ekey</code>, is the middle
* bytes of the ciphertext.</li>
* <li>Take the first 20 bytes of the encrypted key as a seed value, <code>K[0]</code>.</li>
* <li>Compute <code>K[1] ... K[n]</code>, where <code>|K[i]| = 20</code>, <code>n = ceil(|ekey| / 20)</code>, and
* <code>K[i] = SHA-1(UTF-16BE(password) + K[i-1])</code>.</li>
* <li><code>key = ekey ^ (K[1] + ... + K[n])</code>.</li>
* <li>The last 20 bytes are the checksum, computed as <code>H =
* SHA-1(UTF-16BE(password) + key)</code>. If this value does not match the last 20 bytes of the ciphertext, output
* <code>FAIL</code>. Otherwise, output <code>key</code>.</li>
* </ol>
*
* <p>
* The signature is defined as <code>SHA-1(UTF-16BE(password) +
* US_ASCII("Mighty Aphrodite") + encoded_keystore)</code> (yup, Sun engineers are just that clever).
*
* <p>
* (Above, SHA-1 denotes the secure hash algorithm, UTF-16BE the big-endian byte representation of a UTF-16 string, and
* US_ASCII the ASCII byte representation of the string.)
*
* <p>
* The original source code by Casey Marshall of this class should be available in the file <a
* href="http://metastatic.org/source/JKS.java">http://metastatic.org/source/JKS.java</a>.
*
* <p>
* Changes by Ken Ellinwood:
* <ul>
* <li>Fixed a NullPointerException in engineLoad(). This method must return gracefully if the keystore input stream is
* null.</li>
* <li>engineGetCertificateEntry() was updated to return the first cert in the chain for private key entries.</li>
* <li>Lowercase the alias names, otherwise keytool chokes on the file created by this code.</li>
* <li>Fixed the integrity check in engineLoad(), previously the exception was never thrown regardless of password
* value.</li>
* </ul>
