WebJul 23, 2024 · Using String() to try and hold arbitrary-valued byte arrays is a bug that results in corruption of data. If you must for some reason encode the encryption result as a String then use something like base-64 encoding. This code also contains the all-too-common Java crypto anti-pattern of Cipher = Cipher.getInstance("RSA").Always specify the full … WebApr 19, 2024 · So here I get the exception: Exception in thread "main" javax.crypto.IllegalBlockSizeException: Data must not be longer than 245 bytes. 2048 / 8 - 11 = 245 bytes.
