for DNS Security
SYNOPSIS

DESCRIPTION
Dnskeygen (DNS Key Generator) is a tool to generate and
maintain keys for DNS Security within the DNS (Domain Name
System). Dnskeygen can generate public and private keys to
authenticate zone data, and shared secret keys to be used
for Request/Transaction signatures.
- D Dnskeygen will generate a DSA/DSS key. ``size''must be one of [512, 576, 640, 704, 768, 832,896, 960, 1024?.
- HDnskeygen will generate an HMAC-MD5 key.``size must be between 128 and 504.-RDnskeygen will generate an RSA key. ``sizemust be between 512 and 4096.-F(RSA only) Use a large exponent for key genera-tion.-z -h -uThese flags define the type of key being gener-ated: Zone (DNS validation) key, Host (host orservice) key or User (e.g. email) key, respec-tively. Each key is only allowed to be one ofthese.-aIndicates that the key CANNOT be used for authen-tication.-cIndicates that the key CANNOT be used for encryp-tion.-p numSets the key's protocol field to num; the defaultis 3 (DNSSEC) if ``-z or ``-h is specifiedand 2 (EMAIL) otherwise. Other accepted valuesare 1 (TLS), 4 (IPSEC), and 255 (ANY).-s numSets the key's strength field to num; the defaultis 0.-n nameSets the key's name to name.DETAILSDnskeygen stores each key in two files:K__ and K The file K contains the private key in a portable format. The file K contains the public key in the DNS zone file format:
