X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters.

An attacker who presented a certificate chain which contained a very large number of names in the SubjectAlternativeName, signed by a CA certificate which contained a large number of name constraints, could cause a denial of service. The problem has been addressed in Botan 3.5.0 and a partial backport has also been applied and is included in Botan 2.19.5."}, {"lang": "es", "value": "Botan es una librer\u00eda de criptograf\u00eda C++.
