Instructions

Generate random string

Use for test codes, temporary IDs, invite codes, or sample data.

Generate test samples without assuming a token standard

Choose length, count and a character pool for test identifiers or samples. Browser random values select characters, so results change on each run.

An example to check

Input and settings

Length 12, count three, digits only, with ambiguous-character filtering off.

Expected result

Three lines of 12-digit strings, potentially with leading zeros.

Store the results as strings; numeric conversion discards leading zeros. Character selection uses modulo and does not promise the strict uniform distribution of a particular cryptographic protocol.

Scope and limitations

  • There is no database uniqueness guarantee. Add collision checks when uniqueness is required.
  • Security tokens also require expiration, permissions and server-side management. Length alone does not establish safety.
