Crypto4 PKI is set of tools designed for management of X.509 certificates, Certificate Revocation Lists and Certificate Signing Requests.1. Certificate Generator is a wizard-like application that lets you generate certificates and certificate requests. Certificate Generator can create both self-signed certificates and certificates, signed by other (CA) certificates. Certificate can be built from scratch (when you enter all information manually) or using pre-generated Certificate Request. Certificate Generation Profiles are used to generate more than one certificate based on common template. Certificate Generator lets you specify algorithms and key length, intended uses of certificates and Certificate Revocation List location. You can save the certificate in CER, PEM (base64-encoded DER), PFX (PKCS#12) and SPC/PVK formats. 2. Certificate Converter lets you take a certificate (and, if needed, private key) in one format and save it in other format. Certificate conversion is a frequent task since various applications use different formats. Supported certificate formats are CER (standard DER format), PEM (base64-encoded DER), PFX (PKCS#12) and P7B/SPC (PKCS#7). Supported private key formats are CER (standard DER format), PEM (base64-encoded DER), PFX (PKCS#12) and PVK. 3. Certificate Manager lets you easily browse Windows Certificate storages and manage certificates. With Certificate Manager you can export and import certificates in DER, PEM, PFX and SPC/PVK formats. You can view certificate files in all supported formats without importing them into Windows storage. You can also save certificate files in another format, thus doing format conversion of the certificate. Certificate Manager lets you easily locate and delete unnecessary certificates. 4. With CRL Manager you can create, modify and search Certificate Revocation Lists and check their signatures.
