### Security level ###
# Considered equivalent to 128, 192 and 256 bit
# NIST levels 1, 3 & 5 respectively
# Additionally there is a fast signature mode (f)
# and a small signature mode (s)
# See the readme and benchmarks for comparison.

### Tree Hash ###
# SPHINCS+ splits the signatures schemes into a simple and a robust 
# variant for each choice of hash function. The robust variant is 
# comes with all the conservative security guarantees given in SPHNICS. 
# The simple variants are pure random oracle instantiations. These 
# instantiations achieve about a factor three speed-up 
# compared to the robust counterparts. This comes at the 
# cost of a purely heuristic security argument.
