1krb5_c_make_checksum - Compute a checksum (operates on keyblock). 2=================================================================== 3 4.. 5 6.. c:function:: krb5_error_code krb5_c_make_checksum(krb5_context context, krb5_cksumtype cksumtype, const krb5_keyblock * key, krb5_keyusage usage, const krb5_data * input, krb5_checksum * cksum) 7 8.. 9 10 11:param: 12 13 **[in]** **context** - Library context 14 15 **[in]** **cksumtype** - Checksum type (0 for mandatory type) 16 17 **[in]** **key** - Encryption key for a keyed checksum 18 19 **[in]** **usage** - Key usage (see KRB5_KEYUSAGE macros) 20 21 **[in]** **input** - Input data 22 23 **[out]** **cksum** - Generated checksum 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 computes a checksum of type *cksumtype* over *input* , using *key* if the checksum type is a keyed checksum. If *cksumtype* is 0 and *key* is non-null, the checksum type will be the mandatory-to-implement checksum type for the key's encryption type. The actual checksum key will be derived from *key* and *usage* if key derivation is specified for the checksum type. The newly created *cksum* must be released by calling krb5_free_checksum_contents() when it is no longer needed. 42 43 44 45 46 47 48 49 50 51 52.. 53 54.. seealso:: 55 krb5_c_verify_checksum() 56 57 58 59 60 61 62.. note:: 63 64 This function is similar to krb5_k_make_checksum(), but operates on keyblock *key* . 65 66 67 68 69
