We are (Greg is ;) in the process of establishing a new threshold signing scheme that will allow us to handle code signing without any single point of failure. But until then, releases will be signed as before, just with a new certificate. As a matter of record, I used the old code-signing key/certificate to sign a message containing the pubkey that matches the new key/certificate. It's attached at the end of this message. The pkcs7 format is rather clunky, but I wanted to include the current signing certificate to make verification easier. I'll leave it to the reader to extract the certificate from a previous release in order to make sure that they match. It was also in the Core git repo until it was removed recently. To verify, you can use something like: openssl smime -verify -in sig.pkcs7 -inform pem -ignore_critical -purpose any - "ignore_critical" setting tells openssl to ignore the Apple-specific critical extensions that it doesn't understand. - "-purpose any" allows the "purpose == smimesign" check to be skipped. This would otherwise fail because this certificate is only authorized to sign code, not arbitrary messages. By now, the signature will probably fail to validate because the certificate has expired. The signed message below is timestamped on the Bitcoin blockchain using OpenTimestamps. See the attached ots file containing the timestamp proof. If the attachment gets scrubbed and doesn't make it to the list, don't be afraid to nag Peter Todd about a mail-friendly format for these proofs :) Regards, Cory expire.txt.sig: -----BEGIN PKCS7----- MIILTwYJKoZIhvcNAQcCoIILQDCCCzwCAQExCzAJBgUrDgMCGgUAMIIDNAYJKoZI hvcNAQcBoIIDJQSCAyFUaGUgY3VycmVudCBCaXRjb2luIENvcmUgbWFjT1MgY29k ZSBzaWduaW5nIGNlcnRpZmljYXRlIGV4cGlyZXMNCmxhdGVyIHRvZGF5LCBKYW51 YXJ5IDExLCAyMDE4Lg0KDQpJbiB0aGUgZnV0dXJlLCBhIHRocmVzaG9sZCBzaWdu YXR1cmUgd2lsbCBiZSB1c2VkIHRvIHNpZ24gbWFjT1MNCnJlbGVhc2VzLCBidXQg c2luY2UgdGhpcyB3YXMgbm90IHJlYWR5IGluIHRpbWUsIGEgdGVtcG9yYXJ5DQpj ZXJ0aWZpY2F0ZSB3aWxsIGxpa2VseSBiZSB1c2VkIGZvciB0aGUgMC4xNiByZWxl YXNlLg0KDQpUaGUgcHVibGljIGtleSB0byBiZSB1c2VkIHdpdGggdGhpcyBuZXcg Y2VydGlmaWNhdGUgaXM6DQoNCi0tLS0tQkVHSU4gUFVCTElDIEtFWS0tLS0tDQpN SUlCSWpBTkJna3Foa2lHOXcwQkFRRUZBQU9DQVE4QU1JSUJDZ0tDQVFFQXF4aWJE Z2pBT09WVXBTY3pVMnBqDQp0UEVpQ0lZeXl2V21EN2VidGhQbzI5WG9xMUJqYWJG NDlCZ3diNkZFaU1haFN5UTY4ZklMSUhDanJ5SUo4RUN1DQpROFJWbVF3cGdhKzV0 OTZiMEM5emN5WTFhcSsrRzIyMVNqNmFpUmVveXZwcHIrZ2poNmNPbktEc1B0Z2pU cGdiDQovOUhuMmtwYzFmZ000ZkRFMlQ2VXZHVHMwd3d5dWNvL21ya0s1LzEySCtq ZUE3QXVNcjBLQTBVSktSS1VOenFhDQo4QjlLalFFektaRGVVVHRYak9vSmIyNkRQ U3hCbXBGd25zWSs2aHBjeFZSSmphNG1FYzRFYnIyb2gxSmVORU5uDQp4WXR3MHRW VWczTUwvWlI2WU9qQVpMY0V0cW5IR2ZOZXVRazJXVm1pYy9JY3d4VEM0cUk4MnFR OGgxQnFpY3pRDQo4UUlEQVFBQg0KLS0tLS1FTkQgUFVCTElDIEtFWS0tLS0tDQqg ggWLMIIFhzCCBG+gAwIBAgIIJ0r1rumyfZAwDQYJKoZIhvcNAQELBQAweTEtMCsG A1UEAwwkRGV2ZWxvcGVyIElEIENlcnRpZmljYXRpb24gQXV0aG9yaXR5MSYwJAYD VQQLDB1BcHBsZSBDZXJ0aWZpY2F0aW9uIEF1dGhvcml0eTETMBEGA1UECgwKQXBw bGUgSW5jLjELMAkGA1UEBhMCVVMwHhcNMTMwMTEwMjIzOTAxWhcNMTgwMTExMjIz OTAxWjCBqDEaMBgGCgmSJomT8ixkAQEMClBCVjRHTFM5SjQxQDA+BgNVBAMMN0Rl dmVsb3BlciBJRCBBcHBsaWNhdGlvbjogQklUQ09JTiBGT1VOREFUSU9OLCBJTkMu LCBUSEUxEzARBgNVBAsMClBCVjRHTFM5SjQxJjAkBgNVBAoMHUJJVENPSU4gRk9V TkRBVElPTiwgSU5DLiwgVEhFMQswCQYDVQQGEwJVUzCCASIwDQYJKoZIhvcNAQEB BQADggEPADCCAQoCggEBALTd5zURuZVoJviusr119aktXksenb9IN9vq6kBbq38v xEk79wkKMES2XfBRh0HxcEizGzhMNy5OCXuTLMaNMihYdfwYSoBoR2foEU+6kjPU nyJ4dQBFLJZJr5/QeQmALmYHEgZ6lwXFD2lU8t92340zeJ4y5LZw5pcEHtH9Iumm YDutOGCkCGXDcjL+5nHhNScJiXHhswM+62o6XXsQiP6EWbM1CsgrGTNLtaa0U/Uv VDwE79YKklSC5Bog2LD0jBcTuveI66mFzqu++L9X9u+ZArtebwCl7BPNQ+uboYy5 uV2dzf8lpNNZLfXCFjoLe9bLICKfZ7ub9V5aC8+GhckCAwEAAaOCAeEwggHdMD4G CCsGAQUFBwEBBDIwMDAuBggrBgEFBQcwAYYiaHR0cDovL29jc3AuYXBwbGUuY29t L29jc3AtZGV2aWQwMTAdBgNVHQ4EFgQUa5xsqKVzcHDiV6NJ2GL7l8elXV4wDAYD VR0TAQH/BAIwADAfBgNVHSMEGDAWgBRXF+2iz9x8mKEQ4Py+hy0s8uMXVDCCAQ4G A1UdIASCAQUwggEBMIH+BgkqhkiG92NkBQEwgfAwKAYIKwYBBQUHAgEWHGh0dHA6 Ly93d3cuYXBwbGUuY29tL2FwcGxlY2EwgcMGCCsGAQUFBwICMIG2DIGzUmVsaWFu Y2Ugb24gdGhpcyBjZXJ0aWZpY2F0ZSBieSBhbnkgcGFydHkgYXNzdW1lcyBhY2Nl cHRhbmNlIG9mIHRoZSB0aGVuIGFwcGxpY2FibGUgc3RhbmRhcmQgdGVybXMgYW5k IGNvbmRpdGlvbnMgb2YgdXNlLCBjZXJ0aWZpY2F0ZSBwb2xpY3kgYW5kIGNlcnRp ZmljYXRpb24gcHJhY3RpY2Ugc3RhdGVtZW50cy4wDgYDVR0PAQH/BAQDAgeAMBYG A1UdJQEB/wQMMAoGCCsGAQUFBwMDMBMGCiqGSIb3Y2QGAQ0BAf8EAgUAMA0GCSqG SIb3DQEBCwUAA4IBAQAfJ0BjID/1dS2aEeVyhAzPzCBjG8vm0gDf+/qfwRn3+yWe L9vSnMdbilwM48IyQWTagjGGcojbsAd/vE4N7NhQyHInoCllNoeor1I5xx+blTaG RBK+dDhJbbdlGCjsLnH/BczGZi5fyEJds9lUIrp1hJidRcUKO76qb/9gc6qNZpl1 vH5klDUuJYt7YhAs+L6rTXDyqcK9maeQr0gaOPsRRAQLLwiQCorPeMTUNsbVMdMw ZYJsR+PxiAnk+nyi7rfiFvPoASAYUuI6OzYL/Fa6QU4/gYyPgic944QYVkaQBnc0 vEP1nXq6LGKwgVGcqJnkr/E2kui5gJoV5C3qll3eMYICYTCCAl0CAQEwgYUweTEt MCsGA1UEAwwkRGV2ZWxvcGVyIElEIENlcnRpZmljYXRpb24gQXV0aG9yaXR5MSYw JAYDVQQLDB1BcHBsZSBDZXJ0aWZpY2F0aW9uIEF1dGhvcml0eTETMBEGA1UECgwK QXBwbGUgSW5jLjELMAkGA1UEBhMCVVMCCCdK9a7psn2QMAkGBSsOAwIaBQCggbEw GAYJKoZIhvcNAQkDMQsGCSqGSIb3DQEHATAcBgkqhkiG9w0BCQUxDxcNMTgwMTEx MTgxMDUwWjAjBgkqhkiG9w0BCQQxFgQUvqCmkSFwZTLWSNhIddUfdxBPQSswUgYJ KoZIhvcNAQkPMUUwQzAKBggqhkiG9w0DBzAOBggqhkiG9w0DAgICAIAwDQYIKoZI hvcNAwICAUAwBwYFKw4DAgcwDQYIKoZIhvcNAwICASgwDQYJKoZIhvcNAQEBBQAE ggEAQadtQ5qePkjvB3xqLeSvN3e6SpoGQGn6Oo57IiUs/9zP3LAziS2pLbOxSlrS WWJ5byt7qHdxg9Hi+8IRK5ppps3TxX49ZtN9xHR0BQECspHhbad++JnLuCVjoW88 tgX6NylWb16xekpKA9D1xsLOaVlxFJry4S9k3wz53ajg7J83jlA5K1j9rcS8dVhZ WjIl12I2AalQ//PXVyu1soF7ieKgyFKeOefGaAOT3ybji1ibYoPfsS/IdnBz7hbn EmHUHDdl2R+TWDf0ADXMqV3qjMuG5osFRUJbeWm5CUne1/w2BdcIkmkvfmzU+Bmh jixGT1Xg83O4e3LL4Bww0rRY6w== -----END PKCS7----- --001a113ccd8efabcfa05628d3346 Content-Type: application/vnd.oasis.opendocument.spreadsheet-template;
