Why 1024-bit RSA keys are not strong enough
RSA keys can be typically 1024 or 2048 bits long, but experts believe that 1024 bit keys could be broken in the near future. But till now it seems to be an infeasible task. Let us learn the mechanism behind RSA algorithm : >> Generating Public Key : Select two prime no's. What is the largest bit RSA encryption to be cracked The paper of this attack is RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis by Daniel Genkin, Adi Shamir and Eran Tromer. Given the quality of the article and the names of the researcher, it is really hard to doubt the paper content. But be wary that press tend to make things worse than they actually are. e.g. a year ago, we had a paper on Freestart collision for full SHA-1 Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto Library July 04, 2017 Mohit Kumar Security boffins have discovered a critical vulnerability in a GnuPG cryptographic library that allowed the researchers to completely break RSA-1024 and successfully extract the secret RSA key to decrypt data.
I need to generate a 1024 bit RSA key for one time use (gets discarded after each run) and pass the public key to a remote client. The remote client expects the key to be "in ASN.1 format as defined in x509". (I know how to make the private key in the first place with openssl, and then how to extract the public key - both in ascii format.

Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto
1024 bit RSA Cracked, new Milestone Researchers at the University of Michigan have achieved a tech-marvel by moving a step further in cracking RSA. The seemingly secure; public key encryption algorithm was last cracked on 7th January, 2010. A 1,024‐bit RSA key is cryptographically equivalent to a 160‐bit elliptic curve cryptosystem key. John wants to produce a message digest of a 2,048-byte message he plans to send to Mary. If he uses the SHA-1 hashing algorithm, what size will the message digest for this particular message be? 1024-bit RSA (RSA_1024) 2048-bit RSA (RSA_2048) 4096-bit RSA (RSA_4096)
