pkcs10 | Go package to parse and create PKCS | TLS library

I have write some code that writes keypair of public and private key in a token. From the keypair, I create pkcs10 and later generate certificate file from it. The certificate file will be inserted to the token. It all run successfully, but somehow the certificate cannot being read by CAPI or Internet Explorer. If i insert a p12 file, it run without a fuss. I suspect that the CKA_LABEL and CKA_ID is the culprit here. In p12, everything use the same name convention. From container, public key, private key, and certificate. However in my method, the container name looks like auto generated. How can i convert it to be same with CKA_ID? Down below is my code in generating keypair that save in container.

I have been searching for the past 2 days now trying to get a solution that decodes base64 in all file type extensions(.png or jpg). All I found was a base64 decoder that only allow one type of extensions.

My Controller:

I'm writing a C# program that will create inf files and then run a certreq -new to generate the CSR and output the contents - On older machines ( Windows server 2008, for instance ) I'm getting a generic error

"[NewRequest] KeyAlgorithm = "ECDSA_P256" <=> KeySpec?

Editing the CSR file manually and removing the KeySpec altogether seems to make the CSR go through, but every guide I see seems to mention the KeySpec, so I'm confused whether I'm doing something wrong or what.

I have a full functional code in V1 of PKI.js and WebCrypto API that add Subject Alternative Name (DNS:) with CSR. I am trying the same with V2, but the code is not running.

Full functional example with Version 1

The V1 example with CSRhelp. This example does not add Subject Alternative Name with CSR.

thanks in advance I am creating the API in symfony 4 for just uploading the base64 image or any file through POSTMAN and I have to move the file to the targeted directory. I have written the below code in the controller. Through controller I am trying to move the file to the directory, but

I am getting the error as :

Uncaught Warning: file_put_contents(images/5c78de505abdd.svg): failed to open stream: No such file or directory {"exception":"[object] (ErrorException(code: 0): Warning: file_put_contents(images/5c78de505abdd.svg): failed to open stream: No such file or directory at /home/ragiththomas/Sites/asco-forum/src/Modules/Forum/ForumController.php:1107)"} []

I am just starting out with Haskell .I am using stack to build my applcation. I am trying to use this library from hackage . http://hackage.haskell.org/package/pkcs10-0.2.0.0/docs/Data-X509-PKCS10.html

I am not able to figure out how to include this in the code . I tried adding X509 and PKCS10 ,PKCS to my cabal file under build depends ,but that doesnt work . Why do I do to use the functions in this library. Any links to a tutorial for this would be great ,I tried looking but could not find any.

I am trying to add custom OID in CSR like this

I am using forge library to create a self signed certificate in .p12 format which generates private-public key pair using WebCryptoAPI. But when i am trying to import the .p12 file in windows certificate store, i am getting the following error :

This link says that there might be issue with private key.

Following is my key generation snippet by webcryptoApi
