🔒 Text Hash Generator
MD5 Hash Generator — + All Popular Hash & Checksum Tools
Generate cryptographic hashes and checksums from text or files. Choose an algorithm (MD5, SHA-family, BLAKE3, Argon2, bcrypt, PBKDF2, CRC32, and more), add a salt or iterations where supported, and copy the result in HEX or Base64.

No. MD5 is vulnerable to collision and preimage attacks and should not be used to store passwords. Use Argon2 or bcrypt with salts and proper cost parameters.
Use SHA256 or BLAKE3 for modern integrity checks. MD5 can be used for quick legacy verification but is less secure against tampering.
CRC32 is an error-detection checksum (fast, short) and not designed to be cryptographically secure. Cryptographic hashes (SHA, BLAKE3) provide collision resistance and are suitable for security checks.
Cryptographic hashes are one-way functions — you cannot reliably reverse them. For weak hashes or short inputs, attackers may use rainbow tables or brute force, which is why salt + slow hash functions are used for passwords.
Yes, salts (unique per password) and a slow key derivation function (Argon2, PBKDF2, bcrypt) dramatically increase security for stored passwords.
