SYNOPSIS

9       openssl crl [-inform PEM|DER] [-outform PEM|DER] [-text] [-in filename]
10       [-out filename] [-noout] [-hash] [-issuer] [-lastupdate] [-nextupdate]
11       [-CAfile file] [-CApath dir]

DESCRIPTION

14       The crl command processes CRL files in DER or PEM format.
15

COMMAND OPTIONS

17       -inform DER|PEM
18           This specifies the input format. DER format is DER encoded CRL
19           structure. PEM (the default) is a base64 encoded version of the DER
20           form with header and footer lines.
21
22       -outform DER|PEM
23           This specifies the output format, the options have the same meaning
24           as the -inform option.
25
26       -in filename
27           This specifies the input filename to read from or standard input if
28           this option is not specified.
29
30       -out filename
31           specifies the output filename to write to or standard output by
32           default.
33
34       -text
35           print out the CRL in text form.
36
37       -noout
38           don't output the encoded version of the CRL.
39
40       -hash
41           output a hash of the issuer name. This can be use to lookup CRLs in
42           a directory by issuer name.
43
44       -issuer
45           output the issuer name.
46
47       -lastupdate
48           output the lastUpdate field.
49
50       -nextupdate
51           output the nextUpdate field.
52
53       -CAfile file
54           verify the signature on a CRL by looking up the issuing certificate
55           in file
56
57       -CApath dir
58           verify the signature on a CRL by looking up the issuing certificate
59           in dir. This directory must be a standard certificate directory:
60           that is a hash of each subject name (using x509 -hash) should be
61           linked to each certificate.
62

NOTES

64       The PEM CRL format uses the header and footer lines:
65
66        -----BEGIN X509 CRL-----
67        -----END X509 CRL-----
68

EXAMPLES

70       Convert a CRL file from PEM to DER:
71
72        openssl crl -in crl.pem -outform DER -out crl.der
73
74       Output the text form of a DER encoded certificate:
75
76        openssl crl -in crl.der -text -noout
77

BUGS

79       Ideally it should be possible to create a CRL using appropriate options
80       and files too.
