Frequently Asked Questions
What hash algorithms are supported?
SHA-256, SHA-384, SHA-512, SHA-1, and MD5. SHA-256 is recommended for most use cases.
Is hashing the same as encryption?
No. Hashing is a one-way function — you cannot reverse a hash to get the original text. Encryption is reversible with a key.
Is my data secure?
Yes. All hashing is done in your browser using the Web Crypto API. No data is sent to any server.
What is MD5 used for?
MD5 is commonly used for checksum verification. It should not be used for security purposes as it has known vulnerabilities.
