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. Incluso con el mismo tiempo esperado de procesos, ¿usar HMAC-SHA256 es más seguro que usar HMAC-SHA-1?

Would you use HMAC-SHA1 or HMAC-SHA256 for message authentication? Yes. That is a semi-serious answer; both are very good choices, assuming, of course, that a Message Authentication Code is the appropriate solution (that is, both sides share a secret key), and you don't need extreme speed. esp: esp: authentication: sha1: sha1: dynamic interface crypto ipsec ikev1 transform-set ASET-SHA esp-aes esp-sha-hmac crypto map VPNMap 10000 match address VPN This function locks the HMAC, SHA, AES and RSA components, so the user has to ensure to call esp_ds_finish_sign() in a timely manner.

ESP_OK if successful, the ds operation was started now and has to be finished with esp_ds_finish_sign() ESP_ERR_INVALID_ARG if one of the parameters is NULL or data->rsa_length is too long or 0 HMAC stands for Keyed-Hashing for Message Authentication. It's a message authentication code obtained by running a cryptographic hash function (like MD5, SHA1, and SHA256) over the data (to be authenticated) and a shared secret key.
