This code relates to DKIM signature verification used in anti-spam efforts. I have a byte[] from s1024._domainkey.yahoo.com that is ASN.1 encoded, but I don't know if that alone contains enough information to materialize a public key. Based on this class , it appears I can convert an ASN.1 key into a X509Certificate Public key, but I need to supply an OID and some ASN.1-encoded parameters. In this example I have metadata that the ASN1 key is: An RSA encoded key (ASN.1 DER-encoded [ITU-X660-1997] RSAPublicKey per RFC3447) Used with either sha1 sha256 hash algorithms Uses an OID relating to the

Currents i am using phpmailer to send mail's. now how its possible to send email in phpmailer with DKIM keys i search in phpmailer Class file and i found the below code /** * DKIM selector. * @type string */ public $DKIM_selector = ''; /** * DKIM Identity. * Usually the email address used as the source of the email * @type string */ public $DKIM_identity = ''; /** * DKIM passphrase. * Used if your key is encrypted. * @type string */ public $DKIM_passphrase = ''; /** * DKIM signing domain name. * @example 'example.com' * @type string */ public $DKIM_domain = ''; /** * DKIM private key file path

I'm using DKIM for JavaMail to sign outgoing mail with DKIM. My private DKIM key is generated with opendkim-genkey -s default -d example.com and looks like this: -----BEGIN RSA PRIVATE KEY----- ABCCXQ...[long string]...SdQaZw9 -----END RSA PRIVATE KEY----- The DKIM for JavaMail library needs the private DKIM key in DER format as stated in their readme file: DKIM for JavaMail needs the private key in DER format, you can transform a PEM key with openssl: openssl pkcs8 -topk8 -nocrypt -in private.key.pem -out private.key.der -outform der I am looking for a way to avoid having to use openssl to

It looks like there are some great libraries out there to do DomainKeys signing of emails on C#/.NET, but I'm having a really hard time finding the same kind of support for PHP. Maybe I'm not looking in the right place? The only one I found is http://php-dkim.sourceforge.net/ ; it looks incredibly hacky and supports PHP4 only. Considering how popular PHP is, and how critical DomainKeys are for email classification as non-spam, I'd expect better tools; do you know of any? Any other tricks you'd recommend? Extra info: I'm using an external SMTP provider because I need to send out thousands of
