Hi Christopher,
you seem to face a strange mixture of algorithm name and its corresponding OID :
1.2.840.113549.1.1.5 means SHA-1 with RSA encryption, waht's a quite common way
to sign ( http://www.alvestrand.no/objectid/1.2.840.113549.1.1.5.html ).
Where do you see this strange message ?
Is it possible to post the PDF ?
Greetings
Andreas

Looking to resolve issue with PDF sig validation for a
signature created in Acrobat 8.
Found a reference to the same problem in the list:

But hit a dead-end with any further news. I have downloaded
latest BC libs (bcprov-*-jdk15-140.jar) and ran a program to list the supported
algorithms, and SHA1with1.2.840.113549.1.1.5 is not listed.
Does anyone have any further info on this with respect to validating
a signature tied to this algorithm?
Thanks.
