NAME
security — Command line interface to keychains and Security framework
SYNOPSIS
security [ −hilqv] [ −p prompt] [command] [command_options] [command_args]
DESCRIPTION
A simple command line interface which lets you administer keychains, manipulate keys and certificates, and
do just about anything the Security framework is capable of from the command line.
By default security will execute the command supplied and report if anything went wrong.
If the −i or −p options are provided, security will enter interactive mode and allow the user to enter
multiple commands on stdin. When EOF is read from stdin security will exit.
Here is a complete list of the options available:
−h If no arguments are specified, show a list of all commands. If arguments are provided, show
usage for each the specified commands. This option is essentially the same as the help com-
mand.
−i Run security in interactive mode. A prompt ( security> by default ) will be displayed
and the user will be able to type commands on stdin until an EOF is encountered.
−l Before security exits, run
/usr/bin/leaks -nocontext
on itself to see if the command(s) you executed had any leaks.
−p prompt
This option implies the −i option but changes the default prompt to the argument specified
instead.
−q Will make security less verbose.
−v Will make security more verbose.
SECURITY COMMAND SUMMARY
security provides a rich variety of commands ( command in the SYNOPSIS ) , each of which often has a
wealth of options, to allow access to the broad functionality provided by the Security framework. However,
you don’t have to master every detail for security to be useful to you.
Here are brief descriptions of all the security commands:

list is used.
−c name Specify certificate to delete by its common name
−Z hash Specify certificate to delete by its SHA-1 hash
−t Also delete user trust settings for this certificate
The certificate to be deleted must be uniquely specified either by a string found in its common
name, or by its SHA-1 hash.
set-identity-preference [ −h] [ −n] [ −c identity] [ −s service] [ −u keyUsage]
[ −Z hash] [keychain...]
Set the preferred identity to use for a service.
−n Specify no identity (clears existing preference for the given service)
−c identity Specify identity by common name of the certificate
−s service Specify service (may be a URL, RFC822 email address, DNS host, or other
name) for which this identity is to be preferred
−u keyUsage Specify key usage (optional)
−Z hash Specify identity by SHA-1 hash of certificate (optional)
The identity is located by searching the specified keychain(s) for a certificate whose common
name contains the given identity string. If no keychains are specified to search, the default search
list is used. Different identity preferences can be set for individual key usages. You can differenti-
ate between two identities which contain the same string by providing a SHA-1 hash of the certifi-

cate (in addition to, or instead of, the name.)
PARTIAL PATHS AND WILDCARDS
Prior to 10.5.4, identity preferences for SSL/TLS client authentication could only be set on a per-
URL basis. The URL being visited had to match the service name exactly for the preference to be
in effect.
In 10.5.4, it became possible to specify identity preferences on a per-server basis, by using a ser-
vice name with a partial path URL to match more specific paths on the same server. For example,
if an identity preference for "https://www.apache-ssl.org/" exists, it will be in effect for
"https://www.apache-ssl.org/cgi/cert-export", and so on. Note that partial path URLs must end
with a trailing slash character.
Starting with 10.6, it is possible to specify identity preferences on a per-domain basis, by using the
wildcard character ’∗’ as the leftmost component of the service name. Unlike SSL wildcards, an
identity preference wildcard can match more than one subdomain. For example, an identity prefer-
ence for the name "∗.army.mil" will match "server1.subdomain1.army.mil" or "server2.subdo-
main2.army.mil". Likewise, a preference for "∗.mil" will match both "server.army.mil" and
"server.navy.mil".
KEY USAGE CODES
0 - preference is in effect for all possible key usages (default)
1 - encryption only
2 - decryption only
4 - signing only
8 - signature verification only
16 - signing with message recovery only
32 - signature verification with message recovery only
64 - key wrapping only
128 - key unwrapping only
256 - key derivation only
To specify more than one usage, add values together.
get-identity-preference [ −h] [ −s service] [ −u keyUsage] [ −p] [ −c] [ −Z]
Get the preferred identity to use for a service.
−s service Specify service (may be a URL, RFC822 email address, DNS host, or other
name)
−u keyUsage Specify key usage (optional)
−p Output identity certificate in pem format
−c Print common name of the preferred identity certificate
−Z Print SHA-1 hash of the preferred identity certificate
create-db [ −aho0] [ −g dl|cspdl] [ −m mode] [name]
Create a db using the DL. If name isn’t provided security will prompt the user to type a
name.
Options:
−a Turn off autocommit
−g dl|cspdl Use the AppleDL (default) or AppleCspDL
−m mode Set the file permissions to mode.
−o Force using openparams argument

−0 Force using version 0 openparams
Examples

export [ −k keychain] [ −t type] [ −f format] [ −w] [ −p format] [ −P passphrase]
[ −o outfile]
Export one or more items from a keychain to one of a number of external representations. If
keychain isn’t provided, items will be exported from the user’s default keychain.
Options:
−k keychain Specify keychain from which item(s) will be exported.
−t type Specify the type of items to export. Possible types are certs, allKeys, pub-
Keys, privKeys, identities, and all. The default is all. An identity consists of
both a certificate and the corresponding provate key.
−f format Specify the format of the exported data. Possible formats are openssl, bsafe,
pkcs7, pkcs8, pkcs12, x509, openssh1, openssh2, and pemseq. The default is
pemseq if more than one item is being exported. The default is openssl if
one key is being exported. The default is x509 if one certificate is being
exported.
−w Specifies that private keys are to be wrapped on export.
−p Specifies that PEM armour is to be applied to the output data.
−P passphrase Specify the wrapping passphrase immediately. The default is to obtain a
secure passphrase via GUI.
−o outfile Write the output data to outfile. Default is to write data to stdout.
Examples
security> export -k login.keychain -t certs -o /tmp/certs.pem
security> export -k newcert.keychain -t identities -f pkcs12 -o /tmp/mycerts.p12
import inputfile [ −k keychain] [ −t type] [ −f format] [ −w] [ −P passphrase]
[options...]
Import one or more items from inputfile into a keychain. If keychain isn’t provided, items
will be imported into the user’s default keychain.
Options:
−k keychain Specify keychain into which item(s) will be imported.
−t type Specify the type of items to import. Possible types are cert, pub, priv, ses-
sion, cert, and agg. Pub, priv, and session refer to keys; agg is one of the
aggregate types (pkcs12 and PEM sequence). The command can often figure
out what item_type an item contains based in the filename and/or item_for-
mat.
−f format Specify the format of the exported data. Possible formats are openssl, bsafe,
raw, pkcs7, pkcs8, pkcs12, x509, openssh1, openssh2, and pemseq. The
command can often figure out what format an item is in based in the file-
name and/or item_type.
−w Specify that private keys are wrapped and must be unwrapped on import.
−x Specify that private keys are non-extractable after being imported.
−P passphrase Specify the unwrapping passphrase immediately. The default is to obtain a
secure passphrase via GUI.

−a attrName attrValue
Specify optional extended attribute name and value. Can be used multiple
times. This is only valid when importing keys.
−A Allow any application to access the imported key without warning (insecure,
not recommended!)

−c certFile Certificate to verify, in DER or PEM format. Can be specified more than
once; leaf certificate has to be specified first.
−r rootCertFile
Root certificate, in DER or PEM format. Can be specified more than once. If
not specified, the system anchor certificates are used. If one root certificate is
specified, and zero (non-root) certificates are specified, the root certificate is
verified against itself.
−p policy Specify verification policy (ssl, smime, codeSign, IPSec, iChat, basic, swUp-
date, pkgSign, pkinitClient, pkinitServer, eap, appleID, macappstore, times-
tamping). Default is basic.

authorize [ −updPiew] [right...]
Authorize requested right(s). The extend-rights flag will be passed by default.
Options:
−u Allow user interaction.
−p Allow returning partial rights.
−d Destroy acquired rights.
−P Pre-authorize rights only.
−l Operate authorization in least privileged mode.
−i Internalize authref passed on stdin.
−e Externalize authref to stdout
−w Wait while holding AuthorizationRef until stdout is closed. This will allow
client to read externalized AuthorizationRef from pipe.
Examples
security> security authorize -ud my-right
Basic authorization of my-right.
security> security -q authorize -uew my-right | security -q authorize -i my-right
Authorizing a right and passing it to another command as a way to add authorization to
shell scripts.
authorizationdb read <right-name>
authorizationdb write <right-name> [allow|deny|<rulename>]
authorizationdb remove <right-name>
Read/Modify authorization policy database. Without a rulename write will read a dictionary as a
plist from stdin.
Examples
security> security authorizationdb read system.privilege.admin > /tmp/aewp-def
Read definition of system.privilege.admin right.
security> security authorizationdb write system.preferences < /tmp/aewp-def
Set system.preferences to definition of system.privilege.admin right.
security> security authorizationdb write system.preferences authenticate-admin
Every change to preferences requires an Admin user to authenticate.
execute-with-privileges <program> [args...]
Execute tool with privileges. On success stdin will be read and forwarded to the tool.

leaks [ −h] [ −cycles] [ −nocontext] [ −nostacks] [ −exclude symbol]
Run /usr/bin/leaks on this process. This can help find memory leaks after running certain
commands.
Options:
−cycles Use a stricter algorithm (See leaks(1) for details).
−nocontext Withhold the hex dumps of the leaked memory.
−nostacks Don’t show stack traces of leaked memory.
−exclude symbol
Ignore leaks called from symbol.
error [ −h] [<error code(s)...>]
Display an error string for the given security-related error code. The error can be in decimal or hex,
e.g. 1234 or 0x1234. Multiple errors can be separated by spaces.
ENVIRONMENT
MallocStackLogging
When using the leaks command or the −l option it’s probably a good idea to set this environ-
ment variable before security is started. Doing so will allow leaks to display symbolic back-
traces.
