Os md5s correspondem a esses e quando executo o seguinte comando:

openssl pkcs12 -export -out azure2.pfx -inkey azure2.key -in azure2.crt

Recebo um arquivo pkcs12 codificado em binário de volta.

No entanto, quando tento fazer uma postagem http, recebo o seguinte erro:

Exceção não capturada: erro asn1 aninhado

Alguma ideia?

EDITAR:

Eu tentei o seguinte:

p12 = OpenSSL::PKCS12.new(File.read("azure2.pfx"))
p p12.certificate
p p12.ca_certs

e recebo saída válida .... Então, o que dá?
