Frequently Asked Questions
What is SHA-2?
SHA-2 (Secure Hash Algorithm 2) is a family of cryptographic hash functions. It includes several hash functions with different output sizes, such as SHA-224, SHA-256, SHA-384, and SHA-512, providing improved security over its predecessor, SHA-1.
How is SHA-2 different from SHA-1?
SHA-2 is more secure than SHA-1, as it produces longer hash values and has a more complex algorithm, making it resistant to collision attacks. SHA-1 has known vulnerabilities that make it less secure for cryptographic purposes.
When to use this tool?
You should use this tool when you need to generate a SHA-256 hash for data integrity checks, digital signatures, or when you need a secure unique identifier for a piece of data.
Is this tool secure?
Yes, this tool is secure as it generates SHA-256 hashes, which are currently considered secure for most applications. However, ensure that you are using it in a secure environment, as the input data is processed client-side.
