See the OpenSSL documentation for EC_KEY_set_public_key()
Returns whether this EC instance has a public key. The public key (EC::Point) can be retrieved with EC#public_key.
Returns a new RSA instance that carries just the public key components.
This method is provided for backwards compatibility. In most cases, there is no need to call this method.
For the purpose of serializing the public key, to PEM or DER encoding of X.509 SubjectPublicKeyInfo format, check PKey#public_to_pem and PKey#public_to_der.
Decrypt string, which has been encrypted with the private key, with the public key. padding defaults to PKCS1_PADDING which is known to be insecure but is kept for backwards compatibility.
Deprecated in version 3.0. Consider using PKey::PKey#sign_raw and PKey::PKey#verify_raw, and PKey::PKey#verify_recover instead.
Encrypt string with the public key. padding defaults to PKCS1_PADDING, which is known to be insecure but is kept for backwards compatibility. The encrypted string output can be decrypted using private_decrypt.
Deprecated in version 3.0. Consider using PKey::PKey#encrypt and PKey::PKey#decrypt instead.
Returns the result of the peer certificates verification. See verify(1) for error values and descriptions.
If no peer certificate was presented X509_V_OK is returned.
Returns the public key associated with the SPKI, an instance of OpenSSL::PKey.
pub - the public key to be set for this instance
Sets the public key to be associated with the SPKI, an instance of OpenSSL::PKey. This should be the public key corresponding to the private key used for signing the SPKI.
Compares this certificate id’s issuer with other and returns true if they are the same.
Update RubyGems software to the latest version.
We want to use the same linker that Ruby uses, so that the linker flags from mkmf work properly.
Updates the TarHeader’s checksum
Returns the issuer certificate of the given certificate if it exists in the trust directory.
