As a talented engineer with a deep understanding of the importance of secure data transmission, I am confident that I can effectively assist you in renewing your digital signature certificate for electronic invoices. Drawing from my experience working with sensitive data and encrypted transfers, I am well-versed in the complexities and intricacies of certifications.
My knowledge in MySQL, coupled with my engineering background, equip me to approach this task strategically and systematically. I understand the process of creating a certificate request (CSR) and private key (.key) using Open Ssl, uploading it to AFIP, then receiving a certificate (.crt). Finally, I can efficiently create a signature file (.p12 or .pfx) to identify your requesting PC by linking the .crt with the private key (.key).
Additionally, my proficiency in Windows Server 2012 will ensure that any installation issues you previously faced will be resolved promptly. Clearing up any confusion you have regarding whether it's a .p12 or .pfx file needed will be a top priority. Trust me to ease your worries about incorrect keys during installation – my meticulousness and attention to detail won't let any stone unturned. By hiring me, you're selecting assured expertise that delivers on-time and within budget – just as you need!
