Apologies for jumping in late; just to note that 1024-bit keys seem to have been accepted until quite recently: https://www.sophos.com/en-us/support/knowledgebase/122327.aspx

BCP 86, which DKIM refers to, makes statements such as "1024-bit RSA moduli will not be factored until about 2037." Should it be updated? Ale -- Small keys are fine for test suites. And I wish 8-bit keys were functional, for illustrative and educational purposes. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
