man dnskeygen (Commandes) - dnskeygen
NAME
SYNOPSIS
DESCRIPTION
(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. must be one of [512, 576, 640, 704, 768, 832, 896, 960, 1024].
- -H
- Dnskeygen will generate an HMAC-MD5 key. must be between 128 and 504.
- -R
- Dnskeygen will generate an RSA key. must be between 512 and 4096.
- -F
- ( RSA only ) Use a large exponent for key generation.
- -z -h -u
- These flags define the type of key being generated: Zone (DNS validation) key, Host (host or service) key or User (e.g. email) key, respectively. Each key is only allowed to be one of these.
- -a
- Indicates that the key CANNOT be used for authentication.
- -c
- Indicates that the key CANNOT be used for encryption.
- -p num
- Sets the key's protocol field to num ; the default is 3 (DNSSEC) if or is specified and 2 (EMAIL) otherwise. Other accepted values are 1 (TLS), 4 (IPSEC), and 255 (ANY).
- -s num
- Sets the key's strength field to num ; the default is
- -n name
- Sets the key's name to name .
DETAILS
stores each key in two files: K<name>+<alg>+<footprint>.private and K<name>+<alg>+<footprint>.key The file K<name>+<alg>+<footprint>.private contains the private key in a portable format. The file K<name>+<alg>+<footprint>.key contains the public key in the DNS zone file format:
ENVIRONMENT
No environmental variables are used.
