Configure PGP Signing Key Encryption Properties
Use PGP Encryption properties to configure the Publisher PGP signing key created when you regenerate the key. Publisher signing keys must use an RSA key length of 2048 bits or greater. Legacy 1024-bit signing keys are no longer supported.
Note:
Changing PGP Encryption properties doesn’t modify the current Publisher signing key. The configured values apply only when you regenerate the key. See Regenerate the Publisher Signing Key.
