This implementation failure was used, for example, to extract the signing key used for the PlayStation 3 gaming-console. [3] Another way ECDSA signature may leak private keys is when is generated by a faulty random number generator. Such a failure in random number generation caused users of Android Bitcoin Wallet to lose their funds in August 2013.
Let's Encrypt developers planned to generate an ECDSA root key back in 2015, [44] but then pushed back the plan to early 2016, then to 2019, and finally to 2020. On September 3, 2020, Let’s Encrypt issued six new certificates: one new ECDSA root named "ISRG Root X2", four intermediates, and one cross-sign.
Ed25519 is the EdDSA signature scheme using SHA-512 (SHA-2) and an elliptic curve related to Curve25519 [2] where =, / is the twisted Edwards curve + =, = + and = is the unique point in () whose coordinate is / and whose coordinate is positive.
Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.ECC allows smaller keys to provide equivalent security, compared to cryptosystems based on modular exponentiation in Galois fields, such as the RSA cryptosystem and ElGamal cryptosystem.

For example, the branch office may legitimately request that bank transfer be issued once in a signed message. If the bank doesn't use a system of transaction IDs in their messages to detect which transfers have already happened, someone could illegitimately reuse the same signed message many times to drain an account.
