# [DESCRIPTION](#DESCRIPTION)

This sub-command of [**pki**(1)](/man/enterprise-packages/strongswan/pki.1) is used to create a self-signed certificate.

# [OPTIONS](#OPTIONS)

[**-h, --help**](#h,)

Print usage information with a summary of the available options.

[**-v, --debug level**](#v,)

Set debug level, default: 1.

**-+, --options file**

Read command line options from *file*.

[**-i, --in file**](#i,)

Private key input file. If not given the key is read from *STDIN*.

[**-x, --keyid hex**](#x,)

Smartcard or TPM private key object handle in hex format with an optional 0x prefix.

[**-t, --type type**](#t,)

Type of the input key. Either *priv*, *rsa*, *ecdsa*, *ed25519* or *ed448*, defaults to *priv*.

[**-d, --dn distinguished-name**](#d,)

Subject and issuer distinguished name (DN). Required.

[**-a, --san subjectAltName**](#a,)

subjectAltName extension to include in certificate. Can be used multiple times.

[**-l, --lifetime days**](#l,)

Days the certificate is valid, default: 1095. Ignored if both an absolute start and end time are given.

[**-F, --not-before datetime**](#F,)

Absolute time when the validity of the certificate begins. The datetime format is defined by the **--dateform** option.

[**-T, --not-after datetime**](#T,)

Absolute time when the validity of the certificate ends. The datetime format is defined by the **--dateform** option.

[**-D, --dateform form**](#D,)

[strptime(3)](/man/enterprise-packages/strongswan/strptime.3) format for the **--not-before** and **--not-after** options, default: **%d.%m.%y %T**

[**-s, --serial hex**](#s,)

Serial number in hex. It is randomly allocated by default.

[**-e, --flag flag**](#e,)

Add extendedKeyUsage flag. One of *serverAuth*, *clientAuth*, *crlSign*, or *ocspSigning*. Can be used multiple times.

[**-g, --digest digest**](#g,)

Digest to use for signature creation. One of *md5*, *sha1*, *sha224*, *sha256*, *sha384*, or *sha512*. The default is determined based on the type and size of the signature key.

[**-R, --rsa-padding padding**](#R,)

Padding to use for RSA signatures. Either *pkcs1* or *pss*, defaults to *pkcs1*.

[**-f, --outform encoding**](#f,)

Encoding of the created certificate file. Either *der* (ASN.1 DER) or *pem* (Base64 PEM), defaults to *der*.

[**-b, --ca**](#b,)

Include CA basicConstraint extension in certificate.

[**-o, --ocsp uri**](#o,)

OCSP AuthorityInfoAccess URI to include in certificate. Can be used multiple times.

[**-p, --pathlen len**](#p,)

Set path length constraint.

[**-B, --addrblock block**](#B,)

RFC 3779 address block to include in certificate. *block* is either a CIDR subnet (such as *10.0.0.0/8*) or an arbitrary address range (*192.168.1.7-192.168.1.13*). Can be repeated to include multiple blocks. Please note that the supplied blocks are included in the certificate as is, so for standards compliance, multiple blocks must be supplied in correct order and adjacent blocks must be combined. Refer to RFC 3779 for details.

[**-n, --nc-permitted name**](#n,)

Add permitted NameConstraint extension to certificate. For DNS or email constraints, the identity type is not always detectable by the given name. Use the **dns:** or **email:** prefix to force a constraint type.

[**-N, --nc-excluded name**](#N,)

Add excluded NameConstraint extension to certificate. For DNS or email constraints, the identity type is not always detectable by the given name. Use the **dns:** or **email:** prefix to force a constraint type.

[**-X, --critical oid**](#X,)

Add a critical extension with the given OID.

[**-M, --policy-mapping issuer-oid:subject-oid**](#M,)

Add policyMapping from issuer to subject OID.

[**-E, --policy-explicit len**](#E,)

Add requireExplicitPolicy constraint.

[**-H, --policy-inhibit len**](#H,)

Add inhibitPolicyMapping constraint.

[**-A, --policy-any len**](#A,)

Add inhibitAnyPolicy constraint.

## [Certificate Policy](#Certificate_Policy)

Multiple certificatePolicy extensions can be added. Each with the following information:

[**-P, --cert-policy oid**](#P,)

OID to include in certificatePolicy extension. Required.

[**-C, --cps-uri uri**](#C,)

Certification Practice statement URI for certificatePolicy.

[**-U, --user-notice text**](#U,)

User notice for certificatePolicy.

# [EXAMPLES](#EXAMPLES)

Generate a self-signed certificate using the given RSA key:

```


  pki --self --in key.der --dn "C=CH, O=strongSwan, CN=moon" \


      --san moon.strongswan.org > cert.der
```
