Esp sha hmac

I have tried esp = 3des-sha esp = 3des-sha! can any assist with the correct esp config?

The parameters that follow (esp-des and esp-sha-hmac) are the specific types of encryption or authentication that is supported by the ASA for the VPN tunnel that uses this transform set. Which technique is necessary to ensure a private transfer of data using a VPN? It's also possible to use the hash implementations provided by the gcrypt or openssl plugin together with the hmac plugin. ESP/AH support: k Linux 2.6+ kernel q for AH, AES-GMAC is negotiated as encryption algorithm for ESP n before version 2.6.33 the Linux kernel incorrectly used 96 bit truncation for SHA-256 Produces performance and encryption strength similar to SHA-1. HMAC - Hash-based Message Authentication Code is used to verify both the integrity and authenticity of a message.

HMAC-SHA-1-96 produces a 160-bit authenticator value. For use with either ESP or AH, a truncated value using the first 96 bits MUST be supported.

HMACs are almost similar to digital signatures. I am having problems with the correct config in strongswan for "esp-3des esp-sha-hmac". I have tried esp = 3des-sha esp = 3des-sha!

Escuché que HMAC-SHA256 tarda más tiempo que HMAC-SHA-1. Dado que los recursos del sistema son limitados, voy a aplicar diferentes valores de iteración para que sean más seguros siempre que los requisitos del servicio puedan soportarlo.

For HMAC-SHA1 96 bits is very common truncation, used for instance by IPsec/ESP. VPN traffic received from peer may fail to decrypt when using IPsec proposals that use the authentication algorithm of hmac-sha-256-56. security { ipsec { proposal esp-aes256-sha256-3600 { protocol esp; authentication-algorithm hmac-sha-256-96; encryption-algorithm aes-256-cbc; lifetime-seconds 3600; } } HMAC Integration with AES and SHA: Step 1: A dd an “HMAC” algorithm and a “Text Input” into the existing workspace for encryption purposes.
