NAME

       libipsec-mb - overview of Intel(R) Multi-Buffer Crypto for IPSec library

DESCRIPTION

       Intel  Multi-Buffer  Crypto  for  IPsec  Library provides highly-optimized software crypto
       implementations targeting packet processing applications  such  as  IPsec,  TLS,  Wireless
       (RAN), Cable and MPEG DRM and provides industry-leading performance on a range of Intel(R)
       Processors.
       The library offers API crafted for applications where a buffer is  subject  of  encryption
       and/or integrity operations.
       For  best  processor utilization it uses multi buffer technology for algorithms that don't
       allow multi block processing.
       See more in the Intel White Paper:  "Fast  Multi-buffer  IPsec  Implementations  on  Intel
       Architecture Processors".  Jim Guilford, Sean Gulley, et. al.
       The easiest way to find it is to search the Internet for the title.

   RECOMMENDATIONS
       DES algorithm should be avoided and AES encryption should be used instead.
       3DES is a legacy algorithms and AES encryption is recommended to use instead.
       HMAC-MD5-96 is a legacy algorithm and HMAC-SHA1 is recommended to use instead.
       DES, 3DES and HMAC-MD5-96 are implemented in the library to support legacy applications.
       AES-ECB algorithm should be avoided and AES-CBC or  AES-CNTR  encryption  should  be  used
       instead.

   KEY STORAGE
       The  library  doesn't  offer  any  solution for secure key storage or storage of sensitive
       information.  It is up to application to arrange safe storage of sensitive information.

   API
       The library offers four sets of identical API's. Each set corresponds to one architecture:
       SSE, AVX, AVX2 and AVX512.
       It  comprises  of  init_mb_mgr,  get_next_job, submit_job, get_completed_job and flush_job
       operations.
       init_mb_mgr()  - initializes the instance of the multi-buffer manager
       get_next_job() - obtains pointer to next available job entry
       submit_job()   - submits job for processing
       get_completed_job() - returns already completed jobs
       flush_job()    - flushes multi-buffer manager and completes any outstanding operations.

       The basic usage of the API is presented by this pseudo code:

               init_mb_mgr(&mb_mgr);
               ...
               while (work_to_be_done) {
                       job = get_next_job(&mb_mgr);
                       /* TODO: Fill in job fields */
                       job = submit_job(&mb_mgr);
                       while (job != NULL) {
                               /* TODO: Complete processing on job */
                            job = get_completed_job(&mb_mgr);
                       }
               }

               job = flush_job(&mb_mgr);
               while (job != NULL) {
                       /* TODO: Complete processing on job */
                    job = flush_job(&mb_mgr);
               }

       The library provides more interface functions i.e. single block hash  functions  for  HMAC
       OPAD and IPAD calculations.
