🤖 SHA-256 - Padding Process
This article describes the padding process in the SHA-256 hashing algorithm.
Key Points:
• Input messages are padded to a length congruent to 448 mod 512 bits.
• Padding involves appending a '1' bit, followed by '0' bits, and a 64-bit length representation.
• This ensures consistent input length for the hashing function.
