The purpose of PKCS7BINARY is more just for Windows to work with binary files. It means still using PEM but the file is a win binary (I'm not really a win user so not sure if it's useful but there might be some use cases if it's there). To get to the block size for PHP mcrypt, you can use mcryptgetblocksize, which also defines the block size to be in bytes instead of bits. /. Right-pads the data string with 1 to n bytes according to PKCS#7,. where n is the block size. The size of the result is x times n, where x is at least 1. In cryptography, 'PKCS #7: Cryptographic Message Syntax' (a.k.a. 'CMS') is a standard syntax for storing signed and/or encrypted data. PKCS #7 is one of the family of standards called Public-Key Cryptography Standards (PKCS) created by RSA Laboratories. The latest version, 1.5, is available as RFC 2315. C: php extras openssl openssl.exe pkcs7 -inform DER -in TrustedRootCAs.pb7 -printcerts -text TrustedRootCAs.certs Then, in your PHP application for example, add the following line BEFORE you call curlexec. Opensslpkcs7read (PHP 7 = 7.2.0, PHP 8) opensslpkcs7read — Export the PKCS7 file to an array of PEM certificates.
