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

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.

DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.

3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method.
