Another improvement of ESIGN is encouraged, where the public key is hashed together with the message. This allows to have a security proof in the multi key setting.
Additionally, the lower security of ESIGN compared to RSA-PSS leads to suggest that a common public key is used for ESIGN and RSA-PSS, leaving to the signer the choice between fast signature or better security.
