Types

type AllowedFields 

type AllowedFields struct {
	Subject        bool `json:"subject" yaml:"subject"`
	DNSNames       bool `json:"dns" yaml:"dns"`
	IPAddresses    bool `json:"ip" yaml:"ip"`
	EmailAddresses bool `json:"email" yaml:"email"`
	URIs           bool `json:"uri" yaml:"uri"`
}

AllowedFields provides booleans for fields in the CSR. If a AllowedFields is not present in a CertProfile, all of these fields may be copied from the CSR into the signed certificate. If a AllowedFields *is* present in a CertProfile, only those fields with a `true` value in the AllowedFields may be copied from the CSR to the signed certificate. Note that some of these fields, like Subject, can be provided or partially provided through the API. Since API clients are expected to be trusted, but CSRs are not, fields provided through the API are not subject to validation through this mechanism.

type BasicConstraints 

type BasicConstraints struct {
	IsCA       bool `asn1:"optional"`
	MaxPathLen int  `asn1:"optional,default:-1"`

	Names []X509Name `json:"names" yaml:"names"`
	// SerialNumber of the Subject
	SerialNumber string `json:"serial_number,omitempty" yaml:"serial_number,omitempty"`
	// SAN is Subject Alt Names
	SAN []string `json:"san" yaml:"san"`
	// KeyRequest for generated key
	KeyRequest *KeyRequest `json:"key,omitempty" yaml:"key,omitempty"`
	// Extensions for the cert
	Extensions []X509Extension `json:"extensions,omitempty" yaml:"extensions,omitempty"`
}
