1krb5_c_verify_checksum - Verify a checksum (operates on keyblock). 2==================================================================== 3 4.. 5 6.. c:function:: krb5_error_code krb5_c_verify_checksum(krb5_context context, const krb5_keyblock * key, krb5_keyusage usage, const krb5_data * data, const krb5_checksum * cksum, krb5_boolean * valid) 7 8.. 9 10 11:param: 12 13 **[in]** **context** - Library context 14 15 **[in]** **key** - Encryption key for a keyed checksum 16 17 **[in]** **usage** - *key* usage 18 19 **[in]** **data** - Data to be used to compute a new checksum using *key* to compare *cksum* against 20 21 **[in]** **cksum** - Checksum to be verified 22 23 **[out]** **valid** - Non-zero for success, zero for failure 24 25 26.. 27 28 29:retval: 30 - 0 Success; otherwise - Kerberos error codes 31 32 33.. 34 35 36 37 38 39 40 41This 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. 42 43 44 45 46 47 48 49 50 51 52.. 53 54 55 56 57 58 59.. note:: 60 61 This function is similar to krb5_k_verify_checksum(), but operates on keyblock *key* . 62 63 64 65 66
