NAME

6       openssl-crl, crl - CRL utility
7

SYNOPSIS

9       openssl crl [-help] [-inform PEM|DER] [-outform PEM|DER] [-text] [-in
10       filename] [-out filename] [-nameopt option] [-noout] [-hash] [-issuer]
11       [-lastupdate] [-nextupdate] [-CAfile file] [-CApath dir]
12

DESCRIPTION

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

OPTIONS

17       -help
18           Print out a usage message.
19
20       -inform DER|PEM
21           This specifies the input format. DER format is DER encoded CRL
22           structure. PEM (the default) is a base64 encoded version of the DER
23           form with header and footer lines.
24
25       -outform DER|PEM
26           This specifies the output format, the options have the same meaning
27           and default as the -inform option.
28
29       -in filename
30           This specifies the input filename to read from or standard input if
31           this option is not specified.
32
33       -out filename
34           Specifies the output filename to write to or standard output by
35           default.
36
37       -text
38           Print out the CRL in text form.
39
40       -nameopt option
41           Option which determines how the subject or issuer names are
42           displayed. See the description of -nameopt in x509(1).
43
44       -noout
45           Don't output the encoded version of the CRL.
46
47       -hash
48           Output a hash of the issuer name. This can be use to lookup CRLs in
49           a directory by issuer name.
50
51       -hash_old
52           Outputs the "hash" of the CRL issuer name using the older algorithm
53           as used by OpenSSL before version 1.0.0.
54
55       -issuer
56           Output the issuer name.
57
58       -lastupdate
59           Output the lastUpdate field.
60
61       -nextupdate
62           Output the nextUpdate field.
63
64       -CAfile file
65           Verify the signature on a CRL by looking up the issuing certificate
66           in file.
67
68       -CApath dir
69           Verify the signature on a CRL by looking up the issuing certificate
70           in dir. This directory must be a standard certificate directory:
71           that is a hash of each subject name (using x509 -hash) should be
72           linked to each certificate.
73

NOTES

75       The PEM CRL format uses the header and footer lines:
76
77        -----BEGIN X509 CRL-----
78        -----END X509 CRL-----
79

EXAMPLES

81       Convert a CRL file from PEM to DER:
82
83        openssl crl -in crl.pem -outform DER -out crl.der
84
85       Output the text form of a DER encoded certificate:
86
87        openssl crl -in crl.der -inform DER -text -noout
88

BUGS

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