krb5_c_verify_checksum_iov - Validate a checksum element in IOV array (operates on keyblock).

krb5_error_code krb5_c_verify_checksum_iov(krb5_context context, krb5_cksumtype cksumtype, const krb5_keyblock *key, krb5_keyusage usage, const krb5_crypto_iov *data, size_t num_data, krb5_boolean *valid)

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 types)

[in] data - IOV array

[in] num_data - Size of data

[out] valid - Non-zero for success, zero for failure

retval:

• 0 Success; otherwise - Kerberos error codes

Confirm that the checksum in the KRB5_CRYPTO_TYPE_CHECKSUM element is a valid checksum of the KRB5_CRYPTO_TYPE_DATA and KRB5_CRYPTO_TYPE_SIGN_ONLY regions in the iov.

Note

This function is similar to krb5_k_verify_checksum_iov() , but operates on keyblock key .
