What are the chances that a Rijndael Encryption for two different texts could generate the same encrypted text.
Say I have a plain text
“abc” > encrypts to > “defdefdef”
Can this happen?
“hij” > also encrypts to > “defdefdef”
For the same key, the chances are nil. Different inputs map to different outputs with the same key.
For different keys, there is a minuscule probability that two different texts encrypted with two different keys happen to produce the same cipher text. When I say minuscule, I mean negligible. It is more likely that the Andromeda galaxy will park itself right next to the sun today.
