Description

ssl_stapling_file foo.bar.der;
ssl_stapling  on;

nginx -t then produces:

[emerg] 24249#24249: d2i_OCSP_RESPONSE_bio("foo.bar.der") failed (SSL: error:0D0680A8:asn1 encoding routines:asn1_check_tlen:wrong tag error:0D06C03A:asn1 encoding routines:asn1_d2i_ex_primitive:nested asn1 error error:0D08303A:asn1 encoding routines:asn1_template_noexp_d2i:nested asn1 error:Field=responseStatus, Type=OCSP_RESPONSE)

WIth:

 # ssl_stapling  on;

there is no such error?!

openssl x509 -noout -text -inform der -in foo.bar.der

prints the certificate just fine. Having switched between utf8 and ascii did not make a difference either, same outcome.

openssl asn1parse -inform DER -in foo.bar.der

is also printing the values just fine.

It happens only there and other certificates are not affected.

The ocsp certificate is generated as follows:

openssl genpkey -algorithm EC -pkeyopt ec_paramgen_curve:P-384 -out foo.bar.key.pem -aes-256-cbc
openssl req -config foo_bar_ca.cnf -key foo.bar.key.pem -new -out foo.bar.csr.pem
openssl ca -config foo_bar_ca.cnf -extensions ocsp -days 365 -notext -in foo.bar.csr.pem -out foo.bar.cert.pem
openssl x509 -outform DER -in foo.bar.cert.pem -out foo.bar.cert.der

The -extensions ocsp part of foo_bar_ca.cnf

basicConstraints = CA:FALSE
subjectKeyIdentifier = hash
authorityKeyIdentifier = keyid, issuer
keyUsage = critical, digitalSignature
extendedKeyUsage = critical, OCSPSigning

  • Resolution set to invalid
  • Status changed from new to closed

The "ssl_stapling_file" directive needs an OCSP response obtained from your certificate authority, not a certificate. As you are trying to put a certificate instead, parsing expectedly fails.

Note: See TracTickets for help on using tickets.
