IKE (Internet key Exchange) Mode: Select IKE mode to Main mode or Aggressive mode.
This IKE provides secured key generation and key management.
IKE Proposal:
Hash Function: It is a Message Digest algorithm which coverts any length of a message into
a unique set of bits. It is widely used MD5 (Message Digest) and SHA-1 (Secure Hash
Algorithm)
algorithms.
SHA1 is more resistant to brute-force attacks than MD5, however it is slower.

• MD5: A one-way hashing algorithm that produces a 128−bit hash.
• SHA1: A one-way hashing algorithm that produces a 160−bit hash
• SHA1: A one-way hashing algorithm that produces a 160−bit hash
Encryption: Select the encryption method from the pull-down menu. There are several
options,
DES, 3DES and AES (128, 192 and 256). 3DES and AES are more powerful but increase
latency.
