The name originated from the abbreviation Privacy-enhanced Electronic Mail (PEM), which was the standard for email security. A Certificate Signing Request (CSR) is also supplied in PEM format, which is converted from PKCS10 format. It can contain a separate public certificate but also a public certificate plus CA certificates or it can contain a whole set of certificates including public key, private key, and root certificates of the issuing certification authority. It is a container for storing text-encoded cryptographic data (keys and certificates) and allows easy sending by e-mail, it is defined in RFC 1421 to 1424. ![]() One of the most used formats for storing SSL/TLS certificates. In our help we publish instructions on how to generate a CSR and private key in OpenSSL. We do not recommend creating a certificate request and private key on unknown online sites. It is often also sent directly by e-mail in txt PEM format, together with information about the issuance of the SSL certificate. The information structure in the request is defined using ASN.1 (abstract syntax notation).Īfter the certificate is issued and signed by the certification authority, the certificate is already delivered from the authority in other formats, such as CRT, p7b. The encoding format of the CSR that is inserted into the order and sent to the certification authority is PEM. That is, the domain name, organization, state, and also the public key that the certification authority confirms. The CSR application contains the necessary information for issuing the certificate. The application format is according to PKCS # 10 (Public Key Cryptography Standards) and is defined in RFC 2986 (Certification Request Syntax Specification). The request can be generated directly on the server, in the OpenSSL application or you can easily generate it in the order detail according to this manual, including the private key, after ordering the SSL certificate. CSR (.csr)Ī Certificate Signing Request (CSR) is a certificate request that is passed to a certification authority for certification. A large number of formats were created gradually due to various implementations in operating systems or applications, some were standardized in RFC. These are files that are practically only "boxes" for the location of the certificate and its keys. In connection with SSL certificates, a relatively large number of names such as PEM, CSR, KEY, DER, etc.
