I.e. for userspace stuff? That is obviously the right usage, but Linux cryptoapi does not have userspace interface, so was my question. Actually I was several times already asked after acrypto was closed, how userspace can use new hardware drivers, and frankly I do not know what the best userspace API would look like (in one of the projects I already used all three methods one-by-one and failed to determine the best). Simple char device read/write or ioctl, or blocking/nonblocking syscall over file descriptor, or anything else? -- Evgeniy Polyakov - 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
