# LCG16807 => consumption pattern A => direct elliptic curve key
This is a special and unusual way of generating keys directly from the PRNG output without any BIP39 or BIP32 hashing or derivations.
We're not aware of a specific wallet software with this weak generation pattern.
## Observed Usage
* Bitcoin
* with compressed pubkeys

# LCG48271 => consumption pattern A => direct elliptic curve key
This is a special and unusual way of generating keys directly from the PRNG output without any BIP39 or BIP32 hashing or derivations.
We're not aware of a specific wallet software with this weak generation pattern.
## Observed Usage
* We only investigated usage with Bitcoin.
* So far seen: compressed pubkeys
