QUESTION
I am trying to decrypt the string which is encrypted in c# with same key length and vector.
JAVA CODE
...ANSWER
Answered 2020-Sep-28 at 20:26What a shame that you don't show us the encryption code in C# as it would point us directly to the solution instead of arguing and searching.
The reason for your claiming of "truncating" is not on Java-side (decryption) but on your c# encryption function. Most probably you are using a UTF-16 encoding for your plaintext but on Java-side the standard encoding (UTF-8) takes place.
Below you find a slightly added version of your code with dedicated outputs for your data to be fore sure all data has the right length.
Having a look on the ".doFinal" output we see a value of (hex) "650020005200650071007500650073007400200049004400
" - a lot of "x00" values between each character that is definitely a UTF-16 encoding, so in the end the string value is not "e Request Id
" but "e R e q u e s t I D
".
Changing the "new String" encoding to "new String(original, StandardCharsets.UTF_16LE)
" get the "correct" output of "e Request ID" - but where is the missing
"Duplicat" in the beginning? I'm sure you are getting the (base64 encoded) string of ciphertext by "Array-copying" as well and you are just copy the last 12 (or 24 in UTF-16) bytes of the ciphertext so - what I am believing - you are truncating the ciphertext on C#-side.

QUESTION
I have the following python code which is supposed to use brute force to decrypt secret message. The encryption technique is Ceasarean subsitution i.e. every letter in the alphabet is moved by a certain number of places. My main function is supposed to return the decrypted message with the letters moved by all 26 possible number of places (I hope it makes sense but its basically like ROT13 but we don't know the number. It could be ROT13, ROT5, ROT20 etc.)
The problem is my main function doesn't print out the result from the caesarBreak function.
Thanks in advance!
...ANSWER
Answered 2018-Feb-23 at 04:36Because you didn't ask your main function to print it.
print(caesarBreak(secretmsg))
it did return the result, if you find a place to store it then later you could print it out or do whatever you want with it.
