MD2 Generator

What is the MD2 Hash Generator?

The MD2 hash generator creates a unique string of characters that acts as a password or key. This MD2 hash can be used to encrypt important data, such as for public key infrastructure.

How Does the MD2 Hash Generator Work?

The algorithm iterates over each byte of the auxiliary block 18 times for every 16 bytes of input processed. Once the padded message block is processed, its first incomplete block is used as the hash value.

The MD2 hash generation algorithm involves several steps:

1. Initialize auxiliary arrays and variables. Arrays S, T, and X are created, along with variables L, M, and N.

2. Split the input message into 16-byte blocks. If the last block is shorter than 16 bytes, it is padded with zeros.

3. For each block:

- XOR each byte of the block with the corresponding byte in array X.

- Permute the bytes in array X.

- XOR each byte in array X with the corresponding byte in array S.

- Permute the bytes in array S.

- Use the values in array S to update array T.

4. After processing all blocks, pad the final block with zeros to 16 bytes and append a byte equal to the number of zeros added.

5. Process the final block as described above.

6. Use the resulting array S to form the message hash value.

7. Return the hash value as the result.

The MD2 hash generator works by sequentially processing blocks of the input and updating auxiliary arrays, ultimately producing a hash value used to verify data integrity and authenticity.
