Encryption Algorithm Key Length [bits]

des-cbc 64

3des-cbc 192

aes-cbc 128/192/256

aes-ctr 160/224/288

aes-ctr is not recommended for use with static keys. Only use aes-ctr if IKE (Internet Key Exchange) is

used for establishing keys.

Hash Algorithm

This is the authentication algorithm used to calculate the authentication data field applied across

the encrypted payload. Each algorithm must use a key of a specific length.

Hash Password

This password or key, is used by the authentication algorithm to provide authentication and

integrity. The authentication key can be entered as an ASCII character string in double quotes or

as hexadecimal sequence starting with 0x. If the key is entered as an ASCII string, each character

is treated as an 8-bit quantity. E.g. “12345678” is a 64 bit key, equivalent to

0x3132333435363738.

Security Parameter Index (SPI

)

This is a 32 bit integer that is assigned to the SA. Valid values are 0x100 through 0xFFFFFFFF.

The SPI, in conjunction with the destination IP address and the IPsec protocol, uniquely identify

the SA.
