NAME

       ip-sr - IPv6 Segment Routing management

SYNOPSIS

       ip sr  { COMMAND | help }

       ip sr hmac show

       ip sr hmac set KEYID ALGO

       ip sr tunsrc show

       ip sr tunsrc set ADDRESS

DESCRIPTION

       The ip sr command is used to configure IPv6 Segment Routing (SRv6) internal parameters.

       Those parameters include the mapping between an HMAC key ID and its associated hashing algorithm and secret, and the IPv6 address to use as
       source for encapsulated packets.

       The ip sr hmac set command prompts for a passphrase that will be used as the HMAC secret for the corresponding key ID. A blank passphrase
       removes the mapping.  The currently supported algorithms for ALGO are sha1 and sha256.

       If the tunnel source is set to the address :: (which is the default), then an address of the egress interface will be selected. As this
       operation may hinder performances, it is recommended to set a non-default address.

EXAMPLES

   Configure an HMAC mapping for key ID 42 and hashing algorithm SHA-256
       # ip sr hmac set 42 sha256

   Set the tunnel source address to 2001:db8::1
       # ip sr tunsrc set 2001:db8::1

NAME

       Digest::HMAC - Keyed-Hashing for Message Authentication

SYNOPSIS

	# Functional style
	use Digest::HMAC qw(hmac hmac_hex);
	$digest = hmac($data, $key, &myhash);
	print hmac_hex($data, $key, &myhash);

	# OO style
	use Digest::HMAC;
	$hmac = Digest::HMAC->new($key, "Digest::MyHash");

	$hmac->add($data);
	$hmac->addfile(*FILE);

	$digest = $hmac->digest;
	$digest = $hmac->hexdigest;
	$digest = $hmac->b64digest;

DESCRIPTION

       HMAC is used for message integrity checks between two parties that share a secret key, and works in combination with some other Digest
       algorithm, usually MD5 or SHA-1.  The HMAC mechanism is described in RFC 2104.

       HMAC follow the common "Digest::" interface, but the constructor takes the secret key and the name of some other simple "Digest::" as
       argument.

       The hmac() and hmac_hex() functions and the Digest::HMAC->new() constructor takes an optional $blocksize argument as well.  The HMAC
       algorithm assumes the digester to hash by iterating a basic compression function on blocks of data and the $blocksize should match the
       byte-length of such blocks.

       The default $blocksize is 64 which is suitable for the MD5 and SHA-1 digest functions.  For stronger algorithms the blocksize probably
       needs to be increased.
