How to Use Password Hash
- Enter the plain-text password you wish to hash.
- Select your target hashing algorithm (Bcrypt, Argon2, or Scrypt).
- Adjust the algorithmic workload parameters (like rounds or memory cost) if necessary.
- Click "Hash Password" to generate the secure string.
What Is Password Hash?
Password Hashing is a one-way cryptographic process that transforms a plain-text password into a fixed-length string of characters. Modern algorithms like Bcrypt and Argon2 purposely introduce computational delays (work factors) to thwart rapid brute-force offline attacks.
Frequently Asked Questions
Can a hash be decrypted?
No, hashing is a one-way mathematical function. It cannot be "decrypted" back into the original password, it can only be cracked via brute-force guessing.
Which algorithm is best?
Argon2id is currently the recommended industry standard (winning the Password Hashing Competition), as it provides resistance against both GPU and side-channel attacks. Bcrypt remains a highly reliable and widely compatible legacy choice.
