Data must not be longer than 501 bytes
WebJan 8, 2024 · For example, if you are using a 2048-bit RSA key (which is 256 bytes long), the maximum size of the data that can be encrypted is 245 bytes. To fix this error, you will need to either: Use a larger RSA key : If you need to encrypt data that is larger than the maximum size allowed by the current key, you will need to use a larger key.

WebMar 14, 2011 · Solution 1. You are providing it with 2125 bytes, which is not a multiple of 8. When you are ENcrypting, padding is used to make your input up to a multiple of the block size (so the last input block is full size). When you are DEcrypting, you need to decrypt full blocks, then strip off or ignore any padding in the decrypted output.
