the issue is that 0x80 expresses an indefinite length (i.e. a byte sequence with traling 0x00 0x00), but it got ignored for primitives. this was not an issue in 0.2.0, but got introduced in 9da82ac. As reference, http://lapo.it/asn1js/#BQA results in "invalid tag with undefined length at offset 2". |
