1 krb5_k_verify_checksum - Verify a checksum (operates on opaque key).
2 ======================================================================
6 .. c:function:: krb5_error_code krb5_k_verify_checksum(krb5_context context, krb5_key key, krb5_keyusage usage, const krb5_data * data, const krb5_checksum * cksum, krb5_boolean * valid)
13 **[in]** **context** - Library context
15 **[in]** **key** - Encryption key for a keyed checksum
17 **[in]** **usage** - *key* usage
19 **[in]** **data** - Data to be used to compute a new checksum using *key* to compare *cksum* against
21 **[in]** **cksum** - Checksum to be verified
23 **[out]** **valid** - Non-zero for success, zero for failure
30 - 0 Success; otherwise - Kerberos error codes
41 This function verifies that *cksum* is a valid checksum for *data* . If the checksum type of *cksum* is a keyed checksum, *key* is used to verify the checksum. If the checksum type in *cksum* is 0 and *key* is not NULL, the mandatory checksum type for *key* will be used. The actual checksum key will be derived from *key* and *usage* if key derivation is specified for the checksum type.
61 This function is similar to :c:func:`krb5_c_verify_checksum()` , but operates on opaque *key* .
