Der public key

WebThe DER encoding of a generic SubjectPublicKeyInfo which is always used in X.509 certificates and often in other places (including openssl and Java) adds an outer SEQUENCE and AlgorithmIdentifier and a wrapping BIT STRING giving a total length of 550 octets. If you mean something else, specify it more clearly. WebThe RSA, PKCS#1, SSL and TLS communities use the Distinguished Encoding Rules (DER) encoding of ASN.1 to represent keys and certificates in a portable format. The certificate and key information is stored in the binary DER for ASN.1, and applications providing RSA, SSL and TLS should use DER encoding to parse the data.
