May 19, 2020 · there are two places where i need it: - the first, to build a base 64 encoded hash over a string --> works fine - the second is follow the fiscal element deliver a serial number and a public key base64 coded defined as follow: tseserialNumber base64 string Raw SHA-256 hash over the public key that belongs to the private key generating signatures.
NIST Retires SHA-1 Cryptographic Algorithm | NIST
Dec 15, 2022 · The SHA-1 algorithm, one of the first widely used methods of protecting electronic information, has reached the end of its useful life, according to security experts at the National Institute of Standards and Technology (NIST).
Cryptographic Mechanisms: Recommendations and Key Lengths
The recommended key sizes for RSA and mechanisms based on the discrete log problem in finite fields have been adjusted accordingly. 2018-01 15.12.2017 Fundamental revision of the section on prime number generation. Revision of the statement on SHA-1 due to the publication of a SHA-1 collision.
„Kollisionsangriffe gegen die Zertifikaterstellung mit SHA-1 können von vornherein verhindert werden, wenn folgendes gilt: Es wird das X.509v3 Format gemäß ISIS-MTT verwendet. Die Seriennummer ("serialNumber") des Zertifikats hat eine genügend hohe Entropie h …
Update on SHA-1 | SpringerLink
Finally, we show that for a reduced version of SHA-1, with 53 rounds instead of 80, it is possible to find collisions in less than 2 80 operations. This research was supported financially by the A-SIT, Austria and by the BSI, Germany. Biham, E., Chen, R.: Near-collisions of SHA-0. In: Franklin, M. (ed.) CRYPTO 2004. LNCS, vol. 3152, pp. 290–305.
