Hi i'm having troubles trying to make a self-sign to use in a public key packet. I'm using this way : MD5(0x99(1byte), KEYLEN(2bytes - big endian), KEYDATA, USERID, SIGNATURE TYPE(0x10 - 1byte), CREATION TIME(4bytes - big endian)) this hash is encrypted using the pubkey i'm exporting and the pkcs1 padding. Thanks in advance,
