Pepper vs Salt Storage Lookup
Bounded password-verifier storage distinction; not a complete password architecture or security approval.
Description
Look up the storage distinction between a password-verifier salt and a secret pepper.
Salts and peppers play different roles in password-verifier storage. A per-record salt can be stored alongside a verifier, while a pepper is a separate secret whose protection and rotation need their own design.
When to use this tool
Look up the storage distinction between a password-verifier salt and a secret pepper. Use it when the input measurements and conventions below match the operation you need.
- Prepare component, respecting the measurement basis and boundaries below.
- Compare the worked example with your intended operation before reusing its result.
How to use the tool and how it works
- Enter every field in the input table using the stated units and exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
The tool returns its fixed storage-location reference for the supported selector: salt with the per-record verifier and pepper in separately protected secret storage.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| component | Component. | Exact value: "salt", "pepper" |
| component | Built-in entry |
|---|---|
| "salt" | Unique public per-record salt stored with the verifier. |
| "pepper" | Secret independently managed pepper kept apart from verifier storage; key management and rotation are separate design concerns. |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.reference | The stored entry for the exact selected key; its type may be text, a number or a list. |
{
"input": {
"component": "salt"
},
"output": {
"result": {
"reference": "Unique public per-record salt stored with the verifier."
}
}
}Limitations and assumptions
- No password hashing, secret generation, vault integration or rotation is performed. The note does not select an algorithm or establish the security of an application's key-management design.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Use the applicable protocol specification and a reviewed implementation for real verification, hashing or key management. A format label, probability model or tentative text mapping does not replace that operation. Compare the scope of the nearby tools below before substituting one.
