N = m × P · one integer, one unfactorable program

JavaScript source

P bit length

m (source bytes)

—

P (bits)

—

N (decimal digits)

—

Classical factoring

—

N — the encoded program

Encode a program to see N here.

Decode

Available at 16-bit and 32-bit. Higher bit lengths are the point.

Decoder spec: find the factor of N whose bit-length equals P bits. Divide N by it to recover m. Interpret m as UTF-8 → run as JavaScript.
