WebNov 29, 2011 · Ed25519 keys start life as a 32-byte (256-bit) uniformly random binary seed (e.g. the output of SHA256 on some random input). The seed is then hashed using SHA512, which gets you 64 bytes (512 bits), which is then split into a “left half” (the first 32 bytes) and a “right half”. The left half is massaged into a curve25519 private scalar ...
WebOct 16, 2015 · As for whether collisions are possible- modern key sizes (depending on your desired security) range from 1024 to 4096, which means the prime numbers range from 512 to 2048 bits. That means that your prime numbers are on the order of 2^512: over 150 digits long. We can very roughly estimate the density of primes using 1 / ln (n) (see here ). dickies midland texasWeb1 day ago · April 13, 2024, 1:02 PM PDT.
