Private keys
The type for private keys
type t = [ | `RSA of Mirage_crypto_pk.Rsa.priv| `ED25519 of Mirage_crypto_ec.Ed25519.priv| `P256 of Mirage_crypto_ec.P256.Dsa.priv| `P384 of Mirage_crypto_ec.P384.Dsa.priv| `P521 of Mirage_crypto_ec.P521.Dsa.priv
]The polymorphic variant of private keys.
Constructing private keys
val generate : ?seed:string -> ?bits:int -> X509.Key_type.t -> tgenerate ~seed ~bits type generates a private key of the given key type. The argument bits is only used for the bit length of RSA keys. If seed is provided, this is used to seed the random number generator.
val of_octets :
string ->
X509.Key_type.t ->
(t, [> `Msg of string ]) Stdlib.resultof_octets data type decodes the buffer as private key. Only supported for elliptic curve keys.
val of_string :
?seed_or_data:[ `Seed | `Data ] ->
?bits:int ->
X509.Key_type.t ->
string ->
(t, [> `Msg of string ]) Stdlib.resultof_string ~seed_or_data ~bits type data attempts to decode the data as a private key. If seed_or_data is provided and `Seed, the data is taken as seed and generate is used. If it is `Data, of_octets is used with the Base64 decoded data. By default, if type is RSA, the data is used as seed, otherwise directly as the private key data.
Operations on private keys
val key_type : t -> X509.Key_type.tkey_type priv is the key type of priv.
val public : t -> X509.Public_key.tpublic priv is the corresponding public key of priv.
Cryptographic sign operation
Decoding and encoding in ASN.1 DER and PEM format
val encode_der : t -> stringencode_der key is der, the encoded private key as PKCS8 (RFC 5208, Section 5) PrivateKeyInfo structure.
val encode_pem : t -> stringencode_pem key is pem, the encoded private key (using PRIVATE KEY).
