P7B files can be stored in several formats depending on their content and the specific PKCS #7 standard implementation. Some of the most common formats you may encounter include:

SignedData: This format contains encrypted content, digital signatures, and the issuer's certificate.
EnvelopedData: This format includes encrypted content, encryption keys, and receiver certificates.
SignedAndEnvelopedData: This format combines the features of both SignedData and EnvelopedData; it includes encrypted content, digital signatures, and receiver certificates.

Opening and Using P7B Files

As P7B files carry crucial security information, it's essential to handle them correctly. Several applications support the opening and usage of P7B files, with common tasks such as importing a certificate or viewing the file's contents. Some popular applications include:

OpenSSL: A widely-used open-source toolkit for SSL and TLS protocols that supports operations on P7B files. Commands like 'openssl pkcs7' can be used to perform actions like viewing and exporting certificates from the P7B file.
Certutil: A command-line utility available in Windows systems designed for managing and troubleshooting certificates, CRLs, and certificate trust lists. Users can import certificates using the 'certutil -addstore' command.
Microsoft PowerShell: Through the use of the PKIX module in PowerShell, P7B files can be imported and managed with commands such as 'Import-PfxCertificate' and 'Get-PfxData'.
