Cryptographic algorithm support for IPsec and IKE

The devices support cryptographic algorithms to protect classified information. The following algorithms are supported for IPsec: 

• Diffie-Hellman Group 15 
• Diffie-Hellman Group 16 
• Diffie-Hellman Group 21 
• HMAC-SHA-512 
• HMAC-SHA-384 

The following algorithms are supported for IKE: 

• Diffie-Hellman Group 15 
• Diffie-Hellman Group 16 
• Diffie-Hellman Group 21 
• SHA-512 
• ECDSA-521 for X509 signatures
