Verifying and setting file permissions for public/private keys and certificates use the following file mode masks. The *Perms modes are the desired permissions, while the *PermsMask consts are such that perms && mask should always be 0. The mask is only needed because _technically_ I suppose you could make a public key mode 600 or something if you really wanted.

Types

type Cert 

type Cert struct {
	// contains filtered or unexported fields
}

func (File) FilePermsValid 

func (o File) FilePermsValid(goodBits fs.FileMode) (bool, error)

func (File) Match 

func (o File) Match(probe string) bool

Overrides Option.Match to account for relative paths potentially being different strings but representing the same file.

func (File) Open 

func (o File) Open() (*os.File, error)

func (File) OpenFile added in v0.2.0 

func (o File) OpenFile(flag int, perm os.FileMode) (*os.File, error)

func (File) Stat 

func (o File) Stat() (stat fs.FileInfo, err error)

func (File) String 

func (o File) String() string

Override the String() method from the inner Str just so we return the correct None[Type] string.

func (File) Type 

func (o File) Type() string

Override the Type() method from the inner Str. Part of the flag.Value interface.

func (File) WriteFile added in v0.2.0 

func (o File) WriteFile(data []byte, perm os.FileMode) (err error)

type FileOptionError added in v0.2.0 

type FileOptionError struct {
	// contains filtered or unexported fields
}

func (FileOptionError) Error added in v0.2.0 

func (e FileOptionError) Error() string

type PrivateKey 

type PrivateKey struct {
	// contains filtered or unexported fields
}

PubKey wraps an optional path string and provides extra methods for reading, decoding, and writing pem files containing "* PRIVATE KEY" blocks.

func NoPrivateKey 

func NoPrivateKey() PrivateKey

func SomePrivateKey 

func SomePrivateKey(path string) (PrivateKey, error)

func (o PrivateKey) ReadBlocks() (blocks []*pem.Block, err error)

func (PrivateKey) ReadCert 

func (o PrivateKey) ReadCert(in Cert) (cert tls.Certificate, err error)

ReadCert accepts a Cert struct and returns a tls.Certificate for the keypair if both Optionals are Some. This is going to be the most used case for anyone loading

func (PrivateKey) ReadPrivateKey 

func (o PrivateKey) ReadPrivateKey() (key any, err error)

ReadPrivateKey will return the first private key found in the given filepath or error. This may return an *rsa.PrivateKey, *ecdsa.PrivateKey, ed25519.PrivateKey (Note: that is not a pointer), or *ecdh.PrivateKey, depending on the contents of the file.
