Please look to patch description. normally OpenSSL API use looks like:
http://www.openssl.org/docs/crypto/sha.html# SHA1_Init() SHA1_Update() ... .. SHA1_Update() SHA1_Final() This is how openssl like api looks like int cryptodev_open(CRYPTO_CTX *ctx) { /* Open the crypto device */ ctx->fd = open("/dev/crypto", O_RDWR, 0); if (ctx->fd < 0) { perror("open(/dev/crypto)"); return 1; } /* Clone file descriptor */ if (ioctl(ctx->fd, CRIOGET, &ctx->cfd)) { perror("ioctl(CRIOGET)"); return 1; } /* Set close-on-exec (not really neede here) */ if (fcntl(ctx->cfd, F_SETFD, 1) == -1) { perror("fcntl(F_SETFD)"); return 1; } return 0; } int cryptodev_close(CRYPTO_CTX *ctx) { /* Finish crypto session */ if (ioctl(ctx->cfd, CIOCFSESSION, &ctx->sess.ses)) { perror("ioctl(CIOCFSESSION)"); return 1; } /* Close cloned descriptor */ if (close(ctx->cfd)) { perror("close(cfd)"); return 1; } /* Close the original descriptor */ if (close(ctx->fd)) { perror("close(fd)"); return 1; } return 0; } int HASH_Init(SHA_CTX *ctx, int mac) { if (cryptodev_open(ctx)) return 0; /* SHA1 plain test */ memset(&ctx->sess, 0, sizeof(ctx->sess)); ctx->sess.cipher = 0; ctx->sess.mac = mac; if (ioctl(ctx->cfd, CIOCGSESSION, &ctx->sess)) { perror("ioctl(CIOCGSESSION)"); return 0; } return 1; } int HASH_Update(SHA_CTX *ctx, const void *data, unsigned long len) { struct crypt_op cryp; cryp.ses = ctx->sess.ses; cryp.len = len; cryp.src = (void *)data; cryp.mac = ctx->mac; cryp.op = COP_ENCRYPT; cryp.flags = COP_FLAG_UPDATE; if (ioctl(ctx->cfd, CIOCCRYPT, &cryp)) { perror("ioctl(CIOCCRYPT)"); return 0; } return 1; } Dmitry Kasatkin (1): multi-update support for hash calculation cryptodev.h | 1 + cryptodev_main.c | 15 +++++++++------ 2 files changed, 10 insertions(+), 6 deletions(-) _______________________________________________ Cryptodev-linux-devel mailing list Cryptodev-linux-devel@gna.org https://mail.gna.org/listinfo/cryptodev-linux-devel
