support of AES in CFB128 mode in NSS. It has been running fine for me for a while btw. Allan, did you mean you built the CFB128 mode yourself using the ECB mode as a primitive, as I suggested? Wan-Teh ___ dev-tech-crypto mailing list dev-t

Allan (beaufour), you should be able to build the CFB128 mode yourself using the ECB mode as a primitive. It seems straightforward to me (because 128 is the block size, you don't need to shift). This way you don't need to wait for the support of AES in CFB128 mode in NSS. Th
