Minimum Certificate Signature RSA Key Length, v1.0

This Trustmark Definition specifies a minimum RSA key size for private keys use with PKI.
NOTE:If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Assessment Step

1
Minimum Certificate Signature RSA Key Length (MinimumCertificateSignatureRSAKeyLength)
Beginning 01/01/2011, are all PKI certificates required to be signed with keys of at least 2048 bits for RSA to be considered valid?

Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.

Conformance Criteria (1)

C1
Beginning 01/01/2011, all valid certificates shall be signed with keys of at least 2048 bits for RSA.
