IRBM Certificate Error: Invalid Signature or Expired Certificate
If your digital signing suddenly fails with a vague or cryptographic error like:
"Invalid signature algorithm"
"Certificate expired or revoked"
"Invalid client certificate"
… it’s almost always due to a broken, corrupted, or outdated IRB certificate setup.
Common Causes
- ❌ Your private key no longer matches the certificate
- ❌ The PEM/CRT file has expired
- ❌ You used a P12 or DER file without converting properly
Step 1: Convert Certificate to PEM Format
Use OpenSSL to convert your IRBM-provided .p12 file to PEM:
openssl pkcs12 -in client.p12 -clcerts -nokeys -out irb_client_cert.pem
openssl pkcs12 -in client.p12 -nocerts -out irb_client_key.pem
Tip: You may need to strip the passphrase for testing.
Step 2: Store Securely
Move the files to your Laravel project:
storage/certs/irb_client_cert.pem
storage/certs/irb_client_key.pem
Update your config:
'irb_client_cert' => storage_path('certs/irb_client_cert.pem'),
'irb_client_key' => storage_path('certs/irb_client_key.pem'),
'irb_client_key_passphrase' => env('IRB_CLIENT_KEY_PASSPHRASE', ''),
Step 3: Validate the Certificate
Use OpenSSL to check expiry:
openssl x509 -in irb_client_cert.pem -noout -dates
Look for output like:
notBefore=Apr 1 00:00:00 2024 GMT
notAfter=Mar 31 23:59:59 2026 GMT
Step 4: Laravel Debug Check
In your IRBXmlSignatureService, log basic cert info:
$certData = openssl_x509_parse($this->certPem);
Log::debug('IRB Cert Subject:', [$certData['subject'] ?? 'Unknown']);
Log::debug('IRB Cert Expiry:', [date('Y-m-d H:i:s', $certData['validTo_time_t'])]);
What If It’s Expired?
Contact IRBM or your appointed CA (e.g. Pos Digicert, MSC Trustgate) to request a renewed or re-issued certificate for MyInvois integration.
