Frequently Asked Questions
What hash algorithms does this tool support?
This tool supports six algorithms: MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit), SHA-384 (384-bit), SHA-512 (512-bit), and Base64 encoding. The SHA algorithms use the browser's native Web Crypto API for accurate and efficient computation.
Is MD5 still secure for password hashing?
No, MD5 is considered cryptographically broken and should not be used for password hashing or security-sensitive applications. It is included here for legacy compatibility and checksum verification. For security purposes, use SHA-256 or stronger algorithms.
What is the difference between SHA-256, SHA-384, and SHA-512?
These are all members of the SHA-2 family with different output lengths. SHA-256 produces a 256-bit hash, SHA-384 produces a 384-bit hash, and SHA-512 produces a 512-bit hash. Longer hashes provide more collision resistance but take slightly more computation.
How does Base64 encoding differ from hashing?
Base64 is an encoding scheme that converts data into a reversible ASCII string, meaning you can decode it back to the original. Hashing, on the other hand, is a one-way function β you cannot reverse a hash to recover the original input.
Can I hash files instead of text?
Currently, this tool only supports text input. To hash a file, you would need to read the file contents as text first. For binary file hashing, consider using command-line tools like sha256sum or openssl.
