Sql-server – will alwaysOn deal with certificates? do I have to do anything

in a database that is part of an availability group (alwayson), in the current primary server I create a certificate and sign some stored procedures using it.

all is working fine so far.

use mydatabase
go


-- check if certificate exist, create otherwise
IF NOT EXISTS(SELECT 1 FROM SYS.CERTIFICATES WHERE NAME = 'dyntsqlcert')
BEGIN
    CREATE CERTIFICATE dyntsqlcert   
    FROM FILE = 'C:\Certificates\dyntsqlcert.cer'   
    WITH PRIVATE KEY (FILE = 'C:\Certificates\dyntsqlKey.pvk',
    ENCRYPTION BY PASSWORD = 'oH8F*%G9pnyqfa', 
    DECRYPTION BY PASSWORD = 'oH8F*%G9pnyqfa');  
 END


--check if a user for the certificate exist, create otherwise
IF NOT EXISTS(SELECT * FROM SYS.database_principals where name ='dyntsql')
BEGIN
    CREATE USER [dyntsql] FOR CERTIFICATE [dyntsqlcert];
END

-- Granting permissions to the tables
        GRANT SELECT ON [app].[applicant] TO [dyntsql];
        GRANT SELECT ON [usr].[user] TO [dyntsql];
        GRANT SELECT ON [usr].[userCountry] TO [dyntsql];
        GRANT SELECT ON [app].[country] TO [dyntsql];
        GRANT SELECT ON [app].[application] TO [dyntsql];
        GRANT SELECT ON [upl].[applicationDocument] TO [dyntsql];
        GRANT SELECT ON [upl].[document] TO [dyntsql];
        GRANT SELECT ON [upl].[applicationDocumentImages] TO [dyntsql];
        GRANT SELECT ON [upl].[ref_documentType] TO [dyntsql];
        GRANT SELECT ON [app].[program] TO [dyntsql];
        GRANT SELECT ON [app].[ref_applicationStatus] TO [dyntsql];
        GRANT SELECT ON [app].[ref_CPIStatus] TO [dyntsql];
        GRANT SELECT ON [app].[applicationItemGroupChange] TO [dyntsql];
        GRANT SELECT ON [app].[applicationComments] TO [dyntsql];
        --GRANT SELECT ON [APIA_Repl_Sub].[repl].[flightChangesHistory] TO [dyntsql];
        GRANT SELECT ON [app].[applicationstatechange] TO [dyntsql];
        GRANT SELECT ON [app].[applicationPlacementInfo] TO [dyntsql];
        GRANT SELECT ON [app].[applicationPreDepartureQuestions] TO [dyntsql];
        GRANT SELECT ON [app].[applicationComments] TO [dyntsql];
        GRANT SELECT ON [app].[ref_visaStatus] TO [dyntsql];
        GRANT SELECT ON [agy].[agency] TO [dyntsql];

--Adding Signature to SPS'
IF NOT EXISTS
(
    SELECT 1
    FROM sys.crypt_properties cp
    JOIN sys.objects o ON cp.major_id = o.object_id
    LEFT JOIN sys.certificates cer ON cp.thumbprint = cer.thumbprint AND
    cp.crypt_type IN ('SPVC', 'CPVC')
    LEFT JOIN sys.asymmetric_keys ak ON cp.thumbprint = ak.thumbprint AND
    cp.crypt_type IN ('SPVA', 'CPVA')
    WHERE o.name = 'usp_sel_workqueue_applicationsWithNewMedia'
)
BEGIN 
    ADD SIGNATURE TO [app].usp_sel_workqueue_applicationsWithNewMedia
    BY  CERTIFICATE [dyntsqlcert] WITH PASSWORD = 'oH8F*%G9pnyqfa';
END

question is,
in the event of a failover, when this current server becomes the secondary, alongside its c:\ drive, would the certificate still be valid?

I should be testing this instead of asking but I don't have a good testing environment in hand.
