I am familiar with typecasting. Booleans, ints, strings, etc.
However while using an extension, more specifically the OpenSSL
extension I have come across a problem I am not entirely familiar with.
I have an array that looks like...
array('config' => 'config/openssl.cnf',
'encrypt_key' => true,
'private_key_type' => 'OPENSSL_KEYTYPE_RSA',
'digest_algorithm' => 'sha256',
'private_key_bits' => 512,
'x509_extensions' => 'usr_cert',
'encrypt_key_cipher' => 'OPENSSL_CIPHER_3DES');
And according to the current OpenSSL documentation regarding the
configuration constants
(http://www.php.net/manual/en/openssl.ciphers.php) the array needs to
have the 'private_key_type' and 'encrypt_key_cipher' elements as an INT
value vs the string they are currently. Like so.
array('private_key_type' => OPENSSL_KEYTYPE_RSA,
'encrypt_key_cipher' => OPENSSL_CIPHER_3DES);
I have tried to perform typecasting these two elements as an int but
because they are specific to the extension I am not certain how I should
go about doing this.
According to the source for php (the openssl.c) file is an internal
attribute that I cannot find an integer value for to set it manually vs.
using the pre-defined constant values mentioned in the docs.
