you asked for 32-bit key because it would be "convenient for java and javascript guys". this is the opposite of "wanting to be universal". obviously, you are not familiar with cryptography at all, otherwise you would know which key sizes are considered secure. also, you would not compare RSA key length with ECC. it would be interesting to observe whether your arrogance will overwhelm common sense and you continue to argue.

256 bits will be enough for quite a long time, unless quantum computers appear (actual ones, not dwave-type), in which case 512 will be as useless as 256.

Looks like my previous reply insulted u, coz now u r discussing my personality.

Of coz I know that EC key length is not "equal" RSA key length, that's why I wrote

I want to implement RSA with 4096 bits.

Regarding "256 bits will be enough for quite a long time"... Well, looks like u've never heard of Ed25519 which would be easier implemented if we had 512-bit numbers, or Curve25519 implementations that require even more bits.

PS: I'm going to stop discussing this issue with u, obviously u r unable to contribute anything valuable.
