DESCRIPTION
This sub-command of pki(1) is used to create a self-signed certificate.

OPTIONS

-h, --help
    Print usage information with a summary of the available options.

-v, --debug level
    Set debug level, default: 1.

-+, --options file
    Read command line options from file.

-i, --in file
    Private key input file. If not given the key is read from STDIN.

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

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

-d, --dn distinguished-name
    Subject and issuer distinguished name (DN). Required.

-a, --san subjectAltName
    subjectAltName extension to include in certificate. Can be used multiple times.

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

-F, --not-before datetime
    Absolute time when the validity of the certificate begins. The datetime format is defined by the --dateform option.

-T, --not-after datetime
    Absolute time when the validity of the certificate ends. The datetime format is defined by the --dateform option.

-D, --dateform form
    strptime(3) format for the --not-before and --not-after options, default: %d.%m.%y %T

-s, --serial hex
    Serial number in hex. It is randomly allocated by default.

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

-g, --digest digest
    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
    Padding to use for RSA signatures. Either pkcs1 or pss, defaults to pkcs1.

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

-b, --ca
    Include CA basicConstraint extension in certificate.

-o, --ocsp uri
    OCSP AuthorityInfoAccess URI to include in certificate. Can be used multiple times.

-p, --pathlen len
    Set path length constraint.

-B, --addrblock block
    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
    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
    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
    Add a critical extension with the given OID.

-M, --policy-mapping issuer-oid:subject-oid
    Add policyMapping from issuer to subject OID.

-E, --policy-explicit len
    Add requireExplicitPolicy constraint.

-H, --policy-inhibit len
    Add inhibitPolicyMapping constraint.

-A, --policy-any len
    Add inhibitAnyPolicy constraint.

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

-P, --cert-policy oid
    OID to include in certificatePolicy extension. Required.

-C, --cps-uri uri
    Certification Practice statement URI for certificatePolicy.

-U, --user-notice text
    User notice for certificatePolicy.

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
