# krb5_k_make_checksum_iov - Fill in a checksum element in IOV array (operates on opaque key)

krb5_error_code krb5_k_make_checksum_iov(krb5_context context, krb5_cksumtype cksumtype, krb5_key key, krb5_keyusage usage, krb5_crypto_iov *data, size_t num_data)

param:

  [in] context - Library context

  [in] cksumtype - Checksum type (0 for mandatory type)

  [in] key - Encryption key for a keyed checksum

  [in] usage - Key usage (see KRB5_KEYUSAGE macros)

  [inout] data - IOV array

  [in] num_data - Size of data

retval:

  - 0 Success; otherwise - Kerberos error codes

Create a checksum in the KRB5_CRYPTO_TYPE_CHECKSUM element over KRB5_CRYPTO_TYPE_DATA and KRB5_CRYPTO_TYPE_SIGN_ONLY chunks in data . Only the KRB5_CRYPTO_TYPE_CHECKSUM region is modified.
