Beginning to become more and more targeted.
It has been a few months I have noticed I am becoming more and more targeted in login attempts on various online services.2FA is active whenever I have a chance however, some services don't offer it (traditional banks for example) as well as I Simply forget where I have accounts.Does anyone have any tips or a guideline on how I can begin to find where the heck I have accounts and begin locking things down? 2FA is on my gmail and hotmail of course.

practicalities of a primenumber rainbow table
how much effort would go in a programm/rainbowtable that goes to all values that you can make with, say, 4096 bit, check if its a prime number, if so, store it, then mutiply with every other found prime numer and store the result with some backlink to the correponding primenumber. how much would it cost in terms of cpu cycles and storage/memory, how good is this problem parallelisable? TL;DR: can such thing practicly break RSA

S/Mime Email security
More context at the bottom of the page.I have to encrypt and sign an email with an attachment per some instructions, but I don't know enough about cryptology to know how to interpret the instructions.I took the instructions below to mean "encrypt only the attachment (not the full e-mail), encrypt it with AES 256, using the RSA public key as the secret, (which means generating a random IV")The problem is that the secret key in C# doesn't appear that it can be more than 32 bytes. If I use the public key byte array, it is 270 bytes and it is not allowed.My guess at this point is that I should NOT be creating the AES key from the RSA public key, but that's where it loses me. Should I be creating a random key, or using the same one, how are they able to decrypt it if they don't have this key?"Using the secure/multipurpose internet mail exchange (S/MIME) standard, the email must be encrypted using AES-256 (AES cipher with a 256-bit key length) and FMCSA’s ELD public key. The message must be signed using the manufacturer’s ELD private key that corresponds with the ELD public key submitted to FMCSA by the provider when self-certifying the ELD.(a) The ELD must attach a file to an email message to be sent using RFC 5321 Simple Mail Transfer Protocol (SMTP) (incorporated by reference, see § 395.38), to a specific email address, which will be shared with the ELD providers during the technology registration process. (b)The file must have the format described in section 4.8.2.1 of this appendix and must be encrypted using the Secure/Multipurpose Internet Mail Extensions as described in RFC 5751 (incorporated by reference, see § 395.38), and the RSA algorithm as 116 described in RFC 4056 (incorporated by reference, see § 395.38), with the FMCSA public key compliant with NIST SP 800-32 (incorporated by reference, see § 395.38) to be provided to the ELD provider at the time of registration. The content must be encrypted using AES in FIPS Publication 197 (incorporated by reference, see § 395.38), and RFC 3565 (incorporated by reference, see § 395.38). (c)The email must be formatted using the RFC 5322 Internet Message Format (incorporated by reference, see § 395.38), as follows: Element Format To : <Address Provided by FMCSA during online registration> From : <Desired return address for confirmation> Subject : ELD records from <ELD Registration ID><’:’> <ELD Identifier> Body : <Output File Comment> Attachment : MIME encoded AES-256 encrypted file with <filename>.<Date string>.<unique identifier>.aes "
