What is Random String Generator?
Random strings assemble characters from selected sets (A–Z, a–z, 0–9, symbols) using secure random indices per position.
Use for US production API keys?
Prefer dedicated secret managers for production; this helps dev/test tokens with high entropy.
Entropy vs length?
Each character adds log2(charset size) bits; 32 chars from alphanumerics ≈ 190 bits.
Symbols and legacy systems?
Some US mainframes restrict punctuation — disable symbols if downstream systems reject them.
