RSA Small

Decrypt Small Message

Decrypt the tiny RSA ciphertext. This is toy arithmetic only, not deployable security.

Example

Decrypt the tiny RSA ciphertext.

highlighted = computed this step

Step 1 — Set up

Set up the exact toy cryptography values.

c, d, n(13, 27, 55)\begin{array}{c|c}\text{c, d, n}&\text{(13, 27, 55)}\end{array}

Step 2 — Plaintext

Compute the highlighted cryptography value.

m7\begin{array}{c|c}\text{m}&\hlmath{\text{7}}\end{array}
cryptography The values in this lesson are deliberately tiny so every modular arithmetic step can be checked exactly.
