Certificate Key Parameters

Encryption Algorithm

The data encryption standard (DES) for encrypting the private key.

The options are:

  • 3DES (Default): The default encryption algorithm.

  • DES: An encryption algorithm that is less secure than 3DES and uses a 56-bit key size.

Password

Certificate key or private key password, which is used to lock the certificate key.

Re-enter Password

The certificate key password re-entered.

Key Size

The length of the certificate key.

  • 1024 (Default): Specifies a key length of 1024 bits.

  • 1536: Specifies a key length of 1536 bits.

  • 2048: Specifies a key length of 2048 bits.

  • 4096: Specifies a key length of 4096 bits.

Signature Algorithm

The required signature algorithm.

The options are:

  • sha1: Indicates Secure Hash Algorithm version 1.

  • sha256 (Default): Indicates Secure Hash Algorithm 256.

  • sha512: Indicates Secure Hash Algorithm 512.

Certificate Request Parameters

Certificate validity

The number of days that indicate a certificate lifetime.

The default value is 1825 days, which is equivalent to 5 years.

Distinguished Name (DN)

The FQDN of the AE Services server in the DNS format. You might also need to provide additional details, such as your company or organization name. Separate each LDAP attribute with a comma and do not use blank spaces. For example:

cn=myaeserver.example.com,ou=myOrganizationalUnit, o=examplecorp,L=Springfield,ST=Illinois,C=US

Certificate key or private key password, which is used to lock the certificate request.

Re-enter Challenge Password

The certificate key password re-entered for validation.

SAN IP Address

IP address for the SAN parameter.

SAN DNS Name

DNS name or the hostname of the SAN parameter.

Key Usage

Digital Signature

To use the public key with a digital signature mechanism to support security services other than non-repudiation, certificate signing, or CRL signing.

To deselect Key Usage options, use Control+Click.

Non-repudiation

To set digital signing within a non-repudiation service.

Key encipherment

To use a certificate with a protocol that encrypts keys.

Data encipherment

To use the public key for data encryption.

Key agreement

To derive the public key without encryption. You can use this key to encrypt messages between the sender and receiver.

Key certificate sign

To use the public key for verification of a signature on certificates. You can use this extension only in CA certificates.

CRL sign

To use the public key for verification of a signature on revocation information, such as a CRL.

Encipher only

To use the public key only for enciphering data while performing a key agreement.

Decipher only

To use the public key only for deciphering data while performing a key agreement.

Extended Key Usage

SSL/TLS Web Server Authentication

To use the certificate for server authentication.

SSL/TLS Web Client Authentication

To use the certificate for client authentication.

Code signing

To use the certificate for code signing.

E-mail Protection (S/MIME)

To use the certificate for email protection.

To deselect Extended Key Usage options, use Control+Click.

SCEP Parameters

SCEP Server URL

The URL of the CA Simple Certificate Enrollment Protocol (SCEP) or server.

CA Certificate Alias

The unique descriptive name for the CA certificate.

CA certificate alias can be a name that you assign or a name that the CA assigns. By default, you must use the name assigned by your CA.

CA Identifier

CA unique identifier.
