| /* The idea of the functions below is as follows: |
| * |
| * - The core MD5 algorithm does not assume that the "important" data |
| * is at the begin of the encryption block, followed by e.g. 0. |
| * Instead, all bits are equally relevant. |
| * |
| * - If some bytes in the input are known to be 0, we may hard-code them. |
| * With the previous property, it is safe to move them to the upper end |
| * of the encryption block to maximize the number of steps that can be |
| * pre-calculated. |
| * |
| * - Variable-length streams will use the upper 8 byte of the last |
| * encryption block to store the stream length in bits (to make 0, 00, |
| * 000, ... etc. produce different hash sums). |
| * |
| * - We will hash at most 63 bytes, i.e. 504 bits. In the standard stream |
| * implementation, the upper 6 bytes of the last encryption block would |
| * be 0. We will put at least one non-NULL value in the last 4 bytes. |
| * Therefore, our input will always be different to a standard MD5 stream |
| * implementation in either block count, content or both. |
| * |
| * - Our length indicator also varies with the number bytes in the input. |
| * Hence, different pseudo-MD5 input length produces different output |
| * (with "cryptographic probability") even if the content is all 0 or |
| * otherwise identical. |
| * |
| * - Collisions between pseudo-MD5 and pseudo-MD5 as well as pseudo-MD5 |
| * and standard MD5 are as likely as any other MD5 collision. |
