SubjectPublicKeyInfo container
RSA or EC public key
Link to this section Functions
Derives the public key from the given RSA or EC private key.
Attempts to parse a public key in DER (binary) format. Unwraps a SubjectPublicKeyInfo style container, if present.
If the data cannot be parsed as a supported public key type, nil
is
returned.
Attempts to parse a public key in PEM format. Unwraps a SubjectPublicKeyInfo style container, if present.
If the data cannot be parsed as a supported public key type, nil
is
returned.
Converts a public key to DER (binary) format.
Options:
:wrap
- Wrap the private key in a SubjectPublicKeyInfo container (default:false
)
Converts a public key to PEM format.
Options:
:wrap
- Wrap the private key in a SubjectPublicKeyInfo container; for RSA public keys this defaults tofalse
, but for EC public keys this option is ignored and the key is always exported in SubjectPublicKeyInfo format
Extracts a public key from a SubjectPublicKeyInfo style container.
Supports the same container structures as wrap/2
.
Wraps a public key in a SubjectPublicKeyInfo (or similar) container.
The following container types are supported:
:SubjectPublicKeyInfo
- standard X.509 structure for storing public keys (default):OTPSubjectPublicKeyInfo
- Erlang/OTP record variant of:SubjectPublicKeyInfo
, for use in the:OTPCertificate
record:CertificationRequestInfo_subjectPKInfo
- for use in a PKCS#10 CertificationRequest (CSR)
