WebJul 14, 2024 · Cipher.getInstance ("RSA/ECB/PKCS1Padding") On the left is the algorithm and on the right the padding. Note that the middle part (ECB) has no meaning for RSA (it is an artifact of using the scheme of symmetric encryption specifying the operation mode in the middle, which is not defined for asymmetric encryption). WebMay 18, 2010 · Chaining mode such as ECB makes no sense for RSA, unless you are doing it wrong. ECB is for block ciphers: the input data is split into equal-size blocks, and each block is encrypted separately. This induces some weaknesses so ECB mode is best avoided for block ciphers.
