Secure SHA-256 Hash Generator

What is a SHA-256 Hash?

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic function that converts any input text into a unique, fixed-size 256-bit (64-character) hexadecimal string. This process is one-way, meaning you cannot reverse the hash to get the original text.

Key Properties:

• Deterministic: The same input text will always produce the exact same SHA-256 hash.
• One-Way Function: It is computationally impossible to determine the original text from its hash.
• Collision Resistant: It is extremely unlikely that two different inputs will produce the same hash.

Common Uses:

• Password Security: Storing password hashes instead of plain text passwords in databases.
• Data Integrity: Verifying that a file or message has not been altered during transmission.
• Blockchain Technology: Securing transactions and blocks in cryptocurrencies like Bitcoin.
