## Members

- index

  The number of this Security Profile Descriptor in the Security Profile Descriptor List.

- flags

  Security Profile Descriptor Flags bitmask, see *enum nbft\_security\_flags*.

- secret\_type

  Secret Type, see *enum nbft\_security\_secret\_type*.

- sec\_chan\_algs

  Secure Channel Algorithm list: an array of bytes whose values are the Security Type (SECTYPE) field, see *enum nvmf\_tcp\_sectype*. NULL if not present in the NBFT heap.

- sec\_chan\_algs\_len

  Length in bytes of *sec\_chan\_algs*.

- auth\_protocols

  Authentication Protocol identifier list. Values are Authentication Protocol Identifiers as defined in the NVM Express Base Specification. NULL if not present in the NBFT heap.

- auth\_protocols\_len

  Length in bytes of *auth\_protocols*.

- cipher\_suites

  Cipher Suite identifier list: raw byte data containing cipher suite identifiers as defined in the IANA TLS Parameters Registry. Each entry is a 16-bit value; the number of entries is *cipher\_suites\_len* / 2. NULL if not present in the NBFT heap.

- cipher\_suites\_len

  Length in bytes of *cipher\_suites*.

- kx\_groups

  KX-HMAC-CHAP key exchange group identifier list. Values are Key Exchange Group Identifiers as defined in the NVM Express Base Specification. NULL if not present in the NBFT heap.

- kx\_groups\_len

  Length in bytes of *kx\_groups*.

- sec\_hash\_funcs

  KX-HMAC-CHAP hash function identifier list, see *enum libnvmf\_hmac\_alg*. NULL if not present in the NBFT heap.

- sec\_hash\_funcs\_len

  Length in bytes of *sec\_hash\_funcs*.

- secret\_keypath

  URI string for the secret key path. The type of the URI is specified by *secret\_type*. NULL if not present.

## Description

All pointer fields refer to storage owned by the parent *struct libnbft\_info*. They must not be freed separately.
