Hash2603 is a versatile cryptographic hash function with variable output lengths and rounds. It can be used to generate hash codes for various purposes, including securing passwords and verifying sensitive information.

To use Hash2603 to generate hash codes, follow these steps:

1. Import the Hash2603 class from the hash2603 module.

   from hash2603 import Hash2603

2. Create a Hash2603 object by providing the input data, which can be a file name, bytes, or text.

   hash_obj = Hash2603("HERE WILL BE FILE NAME OR BYTES OR TEXTS")

3. Define the desired hash length and round. The hash length is specified using the Bn notation, where n is the desired length in bits (e.g., B128 for a 128-bit hash). The round is specified using the URn notation, where n is the desired round (e.g., UR4 for 4 rounds).

4. Call the corresponding hash function to obtain the hash code.

   hash_value = hash_obj.UR4hash128()  # Example: UR4 means 4 rounds and hash128 means 128-bit output

5. Repeat step 4 with different hash lengths and rounds as needed.

Hash2603 supports various hash lengths (B0, B1, B2, B4, B8, B16, B32, B64, B128, B256, B512, B1024) and rounds (UR1 to UR10). Here's a quick reference:

• B0 to B128 can be obtained from UR1 to UR10.
• B256 can be obtained from UR2 to UR10.
• B512 can be obtained from UR4 to UR10.
• B1024 can be obtained from UR9 to UR10.

Below is an example of generating hash codes for different hash lengths and rounds:

# For quick check run test.py 
from hash2603 import Hash2603

hash_obj = Hash2603("HERE WILL BE FILE NAME OR BYTES OR TEXTS")

# Example hash generation for different lengths and rounds
UR1hash0 = hash_obj.UR1hash0()
UR2hash0 = hash_obj.UR2hash0()
# ...

# Print hash values
print("UR1hash0:", UR1hash0)
print("UR2hash0:", UR2hash0)
# ...

# Repeat the process for other hash lengths and rounds

Hash2603 is designed for lightweight cryptographic applications, such as hashing small files, text, or securing passwords. For more security-sensitive applications, consider using Hash2600, a more advanced version of this hash function.
