mbedtls_x509_time_is_future()

int mbedtls_x509_time_is_future

(

const mbedtls_x509_time *

time

)

Check a given mbedtls_x509_time against the system time and tell if it's in the future.

Note

Intended usage is "if( is_future( valid_from ) ) ERROR". Hence the return value of 1 if on internal errors.

Parameters

time	mbedtls_x509_time to check

Returns

1 if the given time is in the future or an error occured, 0 otherwise.

)

Check a given mbedtls_x509_time against the system time and tell if it's in the past.

Note

Intended usage is "if( is_past( valid_to ) ) ERROR". Hence the return value of 1 if on internal errors.

Parameters

time	mbedtls_x509_time to check

Returns

1 if the given time is in the past or an error occured, 0 otherwise.
