Mark SMIME ZMS and press right mouse button. Logical name is left blank (Filled by reading the certificate) This creates a new entry SMIME ZMS in the Trust Manager. Transaction STRUST STRUST – > Environment – > SMIME Identities New entry for an SMIME identity (usually represents a user) This email address should be assigned to a user who acts as the sender of an email. Creating a SMIME IdentityĪ SMIME identity represents an email address in the SAP system. Class 4: Requires a personal appearance at the certification authority to verify certain original documents 2. In this case, it is confirmed in writing that the information is also correct Class 3: The extract from the commercial register or the identity card is also checked. Class 2: Contain not only the e-mail address but also the name and the company or organization. Class 1: Only whether the stored e-mail address exists. The following certificate classes are distinguished. There are many providers of such certificates on the Internet. This provides additional protection by encrypting the content. These e-mail signature certificates guarantee the authorship and immutability of the content. Special protection is provided here by so-called SMIME certificates. But there is another advantage to e-mail encryption with S/MIME: The procedure is already an integral part of many mail programs, whether on the desktop or on mobile devices. If the signature is in order, it means that the content of the email has not been changed. A message remains visible to all, but a cryptographic signature is added that can be verified by the recipient. However: S/MIME offers a signing functionin addition to encryption. In the end, you are forced to either convince all communication partners of the standard used or drive two tracks and use S/MIME and PGP variables. Although the operating principle of both methods is comparable, S/MIME and PGP are not compatible. To send someone an encrypted email, you need the recipient’s public key and your own private key. There is a private key and a public key (certificates at S / MIME). Both S/MIME and PGP are based on the same principle, so-called hybrid encryption.
Neither S/MIME nor PGP have been cracked so far and are considered safe by experts. S/MIME (Secure/Multipurpose Internet Mail Extensions) has been around since 1995, PGP (Pretty Good Privacy) existed a little earlier, so since 1991. 1.1 Encryptionīasically, there are two common methods used for e-mail encryption: S/MIME and PGP. This ensures the integrity of the sender and excludes tampering. As a rule, simply a digital signature is sufficient.
But you don’t have to encrypt every mail the same way. This e-mail can be read or modified on the way to the recipient. In principle, e-mails are sent in plain text.
