# [DESCRIPTION](#DESCRIPTION)

*ldns\_dnssec\_zone\_sign*() signs the given zone with the given keys

**zone**: the zone to sign  
**key\_list**: the list of keys to sign the zone with  
**new\_rrs**: newly created resource records are added to this list, to free them later  
**func**: callback function that decides what to do with old signatures This function takes an ldns\_rr* and an optional void \*arg argument, and returns one of four values: LDNS\_SIGNATURE\_LEAVE\_ADD\_NEW: leave the signature and add a new one for the corresponding key LDNS\_SIGNATURE\_REMOVE\_ADD\_NEW: remove the signature and replace is with a new one from the same key LDNS\_SIGNATURE\_LEAVE\_NO\_ADD: leave the signature and do not add a new one with the corresponding key LDNS\_SIGNATURE\_REMOVE\_NO\_ADD: remove the signature and do not replace

**arg**: optional argument for the callback function  
Returns LDNS\_STATUS\_OK on success, an error code otherwise

*ldns\_dnssec\_zone\_sign\_nsec3*() signs the given zone with the given new zone, with NSEC3

**zone**: the zone to sign  
**key\_list**: the list of keys to sign the zone with  
**new\_rrs**: newly created resource records are added to this list, to free them later  
**func**: callback function that decides what to do with old signatures  
**arg**: optional argument for the callback function  
**algorithm**: the NSEC3 hashing algorithm to use  
**flags**: NSEC3 flags  
**iterations**: the number of NSEC3 hash iterations to use  
**salt\_length**: the length (in octets) of the NSEC3 salt  
**salt**: the NSEC3 salt data  
Returns LDNS\_STATUS\_OK on success, an error code otherwise

*ldns\_dnssec\_zone\_mark\_glue*()

*ldns\_dnssec\_name\_node\_next\_nonglue*() Finds the first dnssec\_name node in the rbtree that is not occluded. It \*does* return names that are partially occluded.

**node**: the first node to check  
Returns the first node that has not been marked as glue, or NULL if not found (TODO: make that LDNS\_RBTREE\_NULL?)

*ldns\_dnssec\_zone\_create\_nsecs*() Adds NSEC records to the given dnssec\_zone

**zone**: the zone to add the records to  
**new\_rrs**: ldns\_rr's created by this function are added to this rr list, so the caller can free them later  
Returns LDNS\_STATUS\_OK on success, an error code otherwise

*ldns\_dnssec\_remove\_signatures*() remove signatures if callback function tells to

**signatures**: list of signatures to check, and possibly remove, depending on the value of the callback  
**key\_list**: these are marked to be used or not, on the return value of the callback  
**func**: this function is called to specify what to do with each signature (and corresponding key)  
**arg**: Optional argument for the callback function  
Returns s pointer to the new signatures rrs (the original passed to this function may have been removed)

*ldns\_dnssec\_zone\_create\_rrsigs*() Adds signatures to the zone

**zone**: the zone to add RRSIG Resource Records to  
**new\_rrs**: the RRSIG RRs that are created are also added to this list, so the caller can free them later  
**key\_list**: list of keys to sign with.  
**func**: Callback function to decide what keys to use and what to do with old signatures  
**arg**: Optional argument for the callback function  
Returns LDNS\_STATUS\_OK on success, error otherwise
