RSA Small

Encrypt Small Message

Encrypt a tiny message representative with RSA arithmetic. This is toy arithmetic only, not deployable security.

cryptography The values in this lesson are deliberately tiny so every modular arithmetic step can be checked exactly.

Example

Encrypt a tiny message representative with RSA arithmetic.

highlighted = computed this step

Step 1 — Range

Compute the highlighted cryptography value.

0 <= m < nTrue\begin{array}{c|c}\text{0 <= m < n}&\hlmath{\text{True}}\end{array}

Step 2 — Power

Compute the highlighted cryptography value.

m power e343\begin{array}{c|c}\text{m power e}&\hlmath{\text{343}}\end{array}

Step 3 — Ciphertext

Compute the highlighted cryptography value.

c13\begin{array}{c|c}\text{c}&\hlmath{\text{13}}\end{array}
