"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. RSA is not a block cipher. " - Cipher.getinstance rsa/ecb/pkcs1padding
