    \defgroup ECCSI_Overview Overview of ECCSI
    ECCSI (Elliptic Curve-Based Certificateless Signatures for Identity-Based Encryption) is specified in RFC 6507 (https://tools.ietf.org/html/rfc6507).

    In Identity-Based cryptography, there is a Key Management Service that generates keys based on an identity for a client.
    The private key (SSK) and public key (PVT) are delivered to the signer and the public key (PVT) only delivered to the verifier on request.\n\n
    wolfCrypt offers the ability to:
      -# Create KMS keys,
      -# Generate signing key pairs,
      -# Validate signing key pairs,
      -# Sign messages and
      -# Verify messages.

    KMS:
      -# Initialize ECCSI Key: wc_InitEccsiKey()
      -# Make and save or load ECCSI Key:
        -# wc_MakeEccsiKey(), wc_ExportEccsiKey(), wc_ExportEccsiPublicKey() or
        -# wc_ImportEccsiKey()
      -# Wait for request:
        -# Receive signing ID from client.
        -# Generate signing key pair from ID: wc_MakeEccsiPair()
        -# Encode result:
          -# For signer, signing key pair: wc_EncodeEccsiPair()
        -# Send KPAK and result
      -# Free ECCSI Key: wc_FreeEccsiKey()

    Client, signer:
      -# Initialize ECCSI Key: wc_InitEccsiKey()
      -# (When signing pair not cached) Request KPAK and signing pair from KMS
        -# Send signing ID to KMS.
        -# Receive signing key pair from KMS.
        -# Load KMS Public Key: wc_ImportEccsiPublicKey()
        -# Decode signing key pair: wc_DecodeEccsiPair()
        -# Validate the key pair: wc_ValidateEccsiPair()
      -# (If not done above) Load KMS Public Key: wc_ImportEccsiPublicKey()
      -# (If not cached) Calculate hash of the ID and PVT: wc_HashEccsiId()
      -# For each message:
        -# Set Hash of Identity: wc_SetEccsiHash()
        -# Sign message: wc_SignEccsiHash()
        -# Send hash ID, message and signature to peer.
      -# Free ECCSI Key: wc_FreeEccsiKey()

    Client, verifier:
      -# Receive hash ID, message and signature from signer.
      -# Request KPAK (if not cached) and PVT (if not cached) for hash ID from KMS.
      -# Receive KPAK (if not cached) and PVT (if not cached) for hash ID from KMS.
      -# Initialize ECCSI Key: wc_InitEccsiKey()
      -# Load KMS Public Key: wc_ImportEccsiPublicKey()
      -# Decode PVT: wc_DecodeEccsiPvtFromSig()
      -# Calculate hash of the ID and PVT: wc_HashEccsiId()
      -# Set ECCSI key pair: wc_SetEccsiPair()
      -# Verify signature of message: wc_VerifyEccsiHash()
      -# Free ECCSI Key: wc_FreeEccsiKey()

    \defgroup SAKKE_Overview Overview of SAKKE Key
    SAKKE (Sakai-Kasahara Key Encryption) is specified in RFC 6508 (https://tools.ietf.org/html/rfc6508).

    The sender must know the identity of the receiver and the KMS Public Key.\n
    The receiver must have obtained a Receiver Secret Key (RSK) for the identity from a KMS in order to derive the secret.

    KMS:
      -# Initialize SAKKE Key: wc_InitSakkeKey()
      -# Make and save or load SAKKE Key:

        -# Encode RSK for transfer to client: wc_EncodeSakkeRsk()
      -# Free SAKKE Key: wc_FreeSakkeKey()

    IoT-Safe (IoT-SIM Applet For Secure End-2-End Communication) is a technology that leverage the SIM as robust,
    scalable and standardized hardware Root of Trust to protect data communication.

    IoT-Safe SSL sessions use the SIM as Hardware Security Module, offloading all the crypto public
    key operations and reducing the attack surface by restricting access to certificate and keys
    to the SIM.

    IoT-Safe support can be enabled on an existing WOLFSSL_CTX context, using wolfSSL_CTX_iotsafe_enable().\n
    Session created within the context can set the parameters for IoT-Safe key and files usage, and enable
    the public keys callback, with wolfSSL_iotsafe_on().

    If compiled in, the module supports IoT-Safe random number generator as source of entropy for wolfCrypt.
