Field Description
be used with hash lengths of 256, 384 or 512 bits.
• @3 &: SHA-2 with 384 bit hash length.
• @3 : SHA-2 with 512 bit hash length.
Depending on the hardware of your device some options may
not be available.
Please note that the quality of the algorithms is subject to relat-
ive aspects and may change due to mathematical or crypto-
graphic developments.
DH Group The Diffie-Hellman group defines the parameter set used as the
basis for the key calculation during phase 1. "MODP" as sup-
ported by bintec elmeg devices stands for "modular exponenti-
ation".
The following groups with their corresponding bit values are
available:
• , :!
• :!
• & :!
• :!
• &, :!
• :!
Depending on the hardware of your device some options may
not be available.
Lifetime Create a lifetime for phase 1 keys.
The following options are available for defining the Lifetime:
• Input in Seconds: Enter the lifetime for phase 1 key in
seconds. The value can be a whole number from 0 to
2147483647. The default value is , which means the
key must be renewed once four hours have elapsed.
• Input in kBytes: Enter the lifetime for phase 1 keys as amount
of data processed in kBytes. The value can be a whole num-
ber from 0 to 2147483647. The default value is , which
means that the number of transmitted kBytes is irrelevant.
