Order your Secure Email for Organization certificate
With Secure Email for Organization certificates, secure emails for your organization on your email domains. These certificates are ideal for securing emails from shared or other email addresses not assigned to a specific individual.
Use your Secure Email certificate to sign and encrypt your organization emails. Signing authenticates your organization as the sender, adding an extra level of assurance for recipients, while encryption protects sensitive email data.
Before you begin
CSR requirements
You must provide a certificate signing request (CSR) before DigiCert can issue your Secure Email for Organization certificate. You can include a CSR with your request. Or, after submitting your request, you can generate it in the browser.
Secure Email certificates support the following algorithms and key lengths:
RSA 2048, 3072, and 4096
ECC p-256 and p-384
Provide a CSR now.
You can only add a CSR when you place your request. After submitting your order, you cannot add or update a CSR.
We only use the public key embedded in the CSR to create your certificate. All other fields in the CSR are ignored. Learn how to Create a CSR (Certificate Signing Request).
Provide a CSR later.
After DigiCert processes your order and you complete the necessary email address validation, we send instructions to the email recipient for generating the CSR and certificate in their browser. Learn how to Generate your client certificate using DigiCert's KeyGen tool.
Email address domain requirements
Before DigiCert can issue your Secure Email for Organization certificate, you must demonstrate control over the domains in the email addresses on the certificate order. In other words, if you add my-organization@example.com, you must complete the domain control validation (DCV) for the email address domain example.com.
Use one of the following domain validation options to demonstrate control over the email address domain:
Prevalidate the domain
CertCentral features a domain prevalidation process that allows you to validate your domains before ordering certificates. Completing the domain validation ahead of time allows for quicker certificate issuance. See Domain prevalidation: Domain control validation (DCV) methods.
Validate the domain as part of the order process
If you add an email address with a new domain or a domain with expired validation, you can complete the domain validation as part of the order process. See Supported DCV methods for validating the domains on certificate orders.
Organization validation
Before DigiCert can issue a Secure Email for Organization certificate, we must validate the organization for SMIME – SMIME Organization Validation. Organization validation is valid for 825 days. See How do we validate your organization.
Use one of the following options to validate your organization:
Prevalidate the organization
CertCentral features an organization prevalidation process that allows you to validate your organization before ordering certificates. Completing the organization validation ahead of time allows for quicker certificate issuance. See Submit an organization for prevalidation.
Validate the organization as part of the order process
If you add a new organization or an organization with expired S/MIME validation, DigiCert will complete the S/MIME organization validation as part of the order process

In the menu, select the algorithm and key size for generating your CSR:
RSA 2048, 3072, or 4096
ECC p-256 or p-384
DigiCert recommends using RSA 2048 unless you have specific reasons for using a different key size (e.g., company policy requires a 3072-bit key size).
Certificate use
By default, DigiCert Secure Email certificates are dual use for signing and encrypting emails. However, you can update the certificate usage to meet your needs.
RSA options
To view and use the RSA options, add an RSA CSR to the request form or generate the CSR via the browser.

Signature Hash
By default, DigiCert issues RSA certificates with a SHA-256 signature hash and RSA signing algorithm. DigiCert recommends using the default RSA settings unless you have specific reasons for using a different key size or signing algorithm (e.g., company policy requires a 3072-bit key size or an RSASSA-PSS signature).
In the menu, select the signature hash and signing algorithm you want DigiCert to use for your certificate:
SHA-256 with RSA
SHA-384 with RSA
SHA-512 with RSA
SHA-256 with RSASSA-PSS
SHA-384 with RSASSA-PSS
SHA-512 with RSASSA-PSS
With ECC certificates, there is a one-to-one correlation between the signature hash and the signing algorithm.
When using the ECC p-256 key size, your certificate includes a SHA-256 signature hash with ECDSA signing algorithm.
When using ECC p-384 as the key size, your certificate includes a SHA-384 signature hash with ECDSA signing algorithm.
중요
The industry does not support issuing ECC certificates with an RSASSA-PSS signing algorithm. If you require an RSASSA-PSS signature, get an RSA certificate instead.
Additional order options
Expand Additional order options and add information as needed.
The information in this section is not required to issue your certificate. Adding comments and messaging are optional.
Additional Renewal Message (optional)
To create a renewal message for this certificate, type a renewal message with information that might be relevant to the certificate’s renewal. Comments and renewal messages are not included in the certificate.

What's next
Before we can issue your certificate, these tasks must be completed:
Demonstrate control over the domains on your order
Complete the domain validation for the email address domains on the order (demonstrate control over the domain). See Supported DCV methods for validating the domains on certificate orders.
Complete organization validation
DigiCert must validate and authenticate your authority to order a certificate for the organization on your certificate order. To do this, we will call a verified phone number to speak with someone who represents you, the certificate requestor, such as the organization or technical contact.
To get organization consent for your certificate order:
Answer the organization/validation phone call (preferred method)*.
After you submit your certificate order, ensure that the organization contact, technical contact, and company receptionist know you’ve ordered a Secure Email for Organization certificate.
Let them know DigiCert will call a verified phone number to speak with one of them to complete organization validation/authentication.
This phone call usually takes place within 24 hours of the order being placed.
Respond to the organization consent message.
If the DigiCert validation agent can’t reach someone who represents you at the verified phone number, they will leave a message with a call-back phone number and a verification code.
Make sure that the organization or technical contact responds to the message and provides the verification code.
