PEM consists of base64 inside a header and trailer line. OpenSSL crashes with embedded newlines. This was mentioned to me by the OpenXPKI project.
See RFC 7468 section 2: Data before the encapsulation boundaries are permitted, and parsers MUST NOT malfunction when processing such data. Furthermore, parsers SHOULD ignore whitespace and other non- base64 characters and MUST handle different newline conventions. Reproducible with the attached PEM certificate request and OpenSSL 1.02h (linux). openssl req -text -in t/csr1.pem unable to load X509 request 3086379164:error:0906D066:PEM routines:PEM_read_bio:bad end line:pem_lib.c:809: This request is valid - although it (intentionally) also exceeds the standard line length. Note that OpenSSL will accept it if re-formatted: | perl -Mwarnings -Mstrict -MMIME::Base64 -e'local $/; my $x = <STDIN>; $x =~ s/.*^(-----BEGIN CERTIFICATE REQUEST-----\r?\n)(.*)^(-----END CERTIFICATE REQUEST-----).*/$1 . encode_base64(decode_base64( $2 )) . $3/ems; print $x' <t/csr1.pem | openssl req -text|| | OpenSSL should accept PEM with embedded whitespace and long lines. -- Timothe Litt ACM Distinguished Engineer -------------------------- This communication may not represent the ACM or my employer's views, if any, on the matters discussed. -- Ticket here: http://rt.openssl.org/Ticket/Display.html?id=4698 Please log in as guest with password guest if prompted
