Unable to extract key information from \"/config/filestore/files_d/partition_d/ to /var/system/tmp/t

[gtsg86]

Hi,

I am trying to create a csr from an existing key  using:

device = bigip.BIGIP(lb,uname,pwd)

csr_created = device.create(f'/mgmt/tm/sys/crypto/csr', csr_o)

where csr is :

csr_o = {'name': f'/{partition_name}/{xl_cert_name}',
'partition': cert.name.split('/')[1],
'adminEmailAddress': email,
'city': cert.city,
'commonName': xl_cert_name,
'country': cert.country,
'emailAddress': email,
'key': key.name,
'organization': cert.organization,
'subjectAlternativeName': cert.subjectAlternativeName,
'sourcePath': f'/config/ssl/ssl.csr/'}

I got the error:

bigrest.common.exceptions.RESTAPIError:
Status:
400
Response Body:

"code": 400,

"errorStack": [],
"apiError": 26214401
}

Please some can help me to solve this error

Have you tried using the DELETE method on the existing CSR, rather than deleting it using tmsh?  The iControlREST API for /tm/sys/crypto/csr appears to support that method.

Are there any errors in /var/log/restjavad.log.0 or /var/log/ltm after you make the request?

Hi  VernonWells,

I looked at the log, i found nothing.

I want to automatise the task of renewing a cert. to do that I want to create a csr based on the existing key.

so i delete the old csr and with this line i want to create a new one. in the lab env that work but not in prod  :

mgmt.tm.util.bash.exec_cmd('run',
utilCmdArgs=f"-c 'tmsh create sys crypto csr {key_found['name']} "
f"admin-email-address \"{csr['adminEmailAddress']}\" "
f"city \"{csr['city']}\" "
f"common-name \"{csr['commonName']}\" "
f"country \"{csr['country']}\" "
f"email-address \"{csr['emailAddress']}\" "
f"key \"{csr['key']}\" "
f"organization \"{csr['organization']}\" "
f"state \"{csr['state']}\" "
f"subject-alternative-name \"{csr['subjectAlternativeName']}\" "

f"'")

i use the python f5.bigip library

thanks

oh! yes I understood the process.

to Renew the csr and keep the same key and cert,  delete the csr and create a new one :

1) delete the old CSR:

csr1 = mgmt.tm.sys.file.ssl_csrs.ssl_csr.load(name=csr_found['name'], partition=partition_name)
csr1.delete()

2) create a new one,  by specifying the key location

csr = mgmt.tm.util.bash.exec_cmd('run',
utilCmdArgs=f"-c 'tmsh create sys crypto csr /{name[1]}/{name[2]} "
f"admin-email-address \"{email}\" "
f"city \"{cert_found['city']}\" "
f"common-name \"{name[2]}\" "
f"country \"{cert_found['country']}\" "
f"email-address \"{email}\" "
f"key \"{key_found['name']}\" "
f"organization \"{cert_found['organization']}\" "
f"state \"{cert_found['state']}\" "
f"subject-alternative-name \"{cert_found['subjectAlternativeName']}\" "
f"'")

Thank you @VernonWells
