ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308 Reference Manual
Description (or Subfield and Description)
From the drop-down list, select one of the following five algorithms to
negotiate the security association (SA):
• DES. Data Encryption Standard (DES).
• 3DES. Triple DES. This is the default algorithm.
• AES-128. Advanced Encryption Standard (AES) with a 128-bits key size.
• AES-192. AES with a 192-bits key size.
• AES-256. AES with a 256-bits key size.
The encryption key for the inbound policy. The length of the key depends on
the selected encryption algorithm:
• DES. Enter 8 characters.
• 3DES. Enter 24 characters.
• AES-128. Enter 16 characters.
• AES-192. Enter 24 characters.
• AES-256. Enter 32 characters.
The encryption key for the outbound policy. The length of the key depends
on the selected encryption algorithm:
• DES. Enter 8 characters.
• 3DES. Enter 24 characters.
• AES-128. Enter 16 characters.
• AES-192. Enter 24 characters.
• AES-256. Enter 32 characters.
The Security Parameters Index (SPI) for the outbound policy. Enter a
hexadecimal value between 3 and 8 characters (for example: 0x1234).
From the drop-down list, select one of the following two algorithms to be
used in the VPN header for the authentication process:
• SHA-1. Hash algorithm that produces a 160-bit digest. This is the default
setting.
• MD5. Hash algorithm that produces a 128-bit digest.
The integrity key for the inbound policy. The length of the key depends on
the selected integrity algorithm:
• MD5. Enter 16 characters.
• SHA-1. Enter 20 characters.
The integrity key for he outbound policy. The length of the key depends on
the selected integrity algorithm:
• MD5. Enter 16 characters.
• SHA-1. Enter 20 characters.
