WebMar 19, 2024 · The appropriate form on crypto-SE is to state it as: in textbook RSA, we get p, q, n, m 1, c 1 , c 2 but not e or d or m 2. Using BSGS we found e 1 such that c 1 = m 1 e 1 mod n. However when we compute a matching private exponent d 1 [e.g. per d 1 := e 1 − 1 mod ( ( p − 1) ( q − 1)) ] then compute m 2 := c 2 d 1 mod n we get an m 2 that ... churches columbia tn
