S/MIME. S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public-key encryption and signing of MIME data. S/MIME is on an IETF standards track and defined in a number of documents, most importantly RFC 8551. It was originally developed by RSA Data Security, and the original specification used the IETF MIME specification [1 ...
PEM data is commonly stored in files with a ".pem" suffix, a ".cer" or ".crt" suffix (for certificates), or a ".key" suffix (for public or private keys). [3] The label inside a PEM file represents the type of the data more accurately than the file suffix, since many different types of data can be saved in a ".pem" file.
List of file signatures. This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.
Credit card security. When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL. As you enter your credit card number, SSL encodes it so it's transmitted in a format that prevents eavesdropping or data theft. When it's received by our secure server, your credit card number is never transmitted over the ...
Technical overview. AS2 is specified in RFC 4130, and is based on HTTP and S/MIME. It was the second AS protocol developed and uses the same signing, encryption and MDN (as defined by RFC3798) conventions used in the original AS1 protocol introduced in the late 1990s by IETF. In other words:
A level 2 signature is highly analogous to the trust assumption users must rely on whenever they use the default certificate authority list (like those included in web browsers); it allows the owner of the key to make other keys certificate authorities. PGP versions have always included a way to cancel ('revoke') public key certificates. A lost ...
The architecture of CMS is built around certificate-based key management, such as the profile defined by the PKIX working group. CMS is used as the key cryptographic component of many other cryptographic standards, such as S/MIME, PKCS #12 and the RFC 3161 digital timestamping protocol.
Public key certificate. In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [1][2] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the ...
