[][src]Function srtp2_sys::srtp_crypto_policy_set_null_cipher_hmac_sha1_80

pub unsafe extern "C" fn srtp_crypto_policy_set_null_cipher_hmac_sha1_80(
    p: *mut srtp_crypto_policy_t
)

@brief srtp_crypto_policy_set_null_cipher_hmac_sha1_80() sets a crypto policy structure to an authentication-only policy

@param p is a pointer to the policy structure to be set

The function call srtp_crypto_policy_set_null_cipher_hmac_sha1_80(&p) sets the srtp_crypto_policy_t at location p to use HMAC-SHA1 with an 80 bit authentication tag to provide message authentication, but to use no encryption. This policy is NOT RECOMMENDED for SRTP unless there is a requirement to forego encryption.

This function is a convenience that helps to avoid dealing directly with the policy data structure. You are encouraged to initialize policy elements with this function call. Doing so may allow your code to be forward compatible with later versions of libSRTP that include more elements in the srtp_crypto_policy_t datatype.

@warning This policy is NOT RECOMMENDED for SRTP unless there is a requirement to forego encryption.

@return void.
