PBKDF2 Key Deriver: Generate Secure Keys from Passwords
PBKDF2 Key Deriver creates a derived key from a password and salt using PBKDF2 with HMAC-SHA256 through WebCrypto in your browser. Set the available options, then generate one or a batch of values for tests, fixtures, or seed data. Increasing the iteration count makes derivation slower and stronger; the supplied guidance is 600,000 or more iterations for SHA-256.
PBKDF2 Key Deriver is a browser-based PBKDF2 key derivation tool for creating a key from a password and salt. It uses PBKDF2 with HMAC-SHA256 through WebCrypto, so you can derive a key from a password in your browser without needing to set up a separate tool. Use it to generate values for testing, fixtures, or seed data.
To use the PBKDF2-SHA256 key generator, provide the password and salt, set the available options, and generate a value or batch. The iteration count matters: a higher count makes derivation slower but stronger. The supplied guidance for SHA-256 is 600,000 or more iterations. Generated values can be copied for use in the task you are working on.
A password is the input to the derivation, while the derived key is the output. PBKDF2 applies a key derivation process to the password and salt rather than simply treating the password itself as the resulting key. This makes the tool useful when you need derived values for test data or want to inspect the result of a PBKDF2-SHA256 setup.
The PBKDF2 Key Deriver runs entirely in your browser: your input is processed on your device, and no data is sent to a server. It is free, requires no signup, and works offline once the page has loaded. Developers and DevOps engineers can use it to prepare test values, fixtures, and seed data without uploading their inputs.
Step 1: Enter the password and salt you want to use. PBKDF2 derives a key from these inputs.
Step 2: Set the available options before starting. The iteration count affects how long derivation takes.
Step 3: Generate the key or batch of values. The tool uses PBKDF2 with HMAC-SHA256 through WebCrypto.
Step 4: Copy the values you need for your tests, fixtures, or seed data.
Use case: Create PBKDF2 values for test fixtures or seed data. This gives your tests concrete derived values to work with.
Use case: Generate a batch of values at once instead of inventing them by hand. This can help when preparing multiple test cases.
Use case: Get generated values that are properly random rather than relying on guesses typed at a keyboard.
Use case: Check how a password and salt produce a derived key with PBKDF2-SHA256. This is useful when reviewing a derivation setup.
Use case: Prepare example values for development or QA workflows. Copy only the values you need into your local test materials.
