Systems, methods, and computer products for flattening electronic signatures, such as the signatures used for DNS zone signing keys. Associated operation may include: obtaining a first electronic signature on a mid-level public key and information associated therewith, wherein the first electronic signature is validatable by a high-level public key; obtaining a low-level public key and information associated therewith; generating a second electronic signature on the low-level public key and the information associated therewith, wherein the second electronic signature is validatable by the mid-level public key; and constructing a third electronic signature comprising the mid-level public key, the information associated therewith, the first electronic signature and the second electronic signature, wherein the third electronic signature is validatable by the high-level public key. Also included are systems, methods, and computer products and media for validating an electronic signature, such as a flattened electronic signature.
