For HMAC mode of MD5, use HASH. Is this correct? Yes. You request them as hmac(sha1) resp. hmac(md5). >>3.

If you can boot v2.6.24-rc8 than you should have no problems with cryptodev. I don't know the diff between denx-linux & linus-linux. >Thanks, >Loc Sebastian - To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
