SHE MUH TRAP QUEEN

i don't do one liners cuz they suck

# faster urandom source using openssl
urandom() {
    head --bytes=128 /dev/urandom 2>/dev/null \
    | base64 \
    | openssl enc -aes-256-ctr \
        -in /dev/zero \
        -nosalt \
        -pass stdin \
        2>/dev/null
}

mostly irrelevant since the kernel cucks made urandom some salsa20 bullshit stream cipher but it's still faster.

this is one i use for colorizing PS1's to differentiate different hosts.

 # $1 - get hash of string
# common colored name algo
color_hash() {
    declare -i chr hash_val i len
    chr=0
    hash_val=0
    len=${#1}
    # i=1 because zsh indexing
    for (( i=1; i<len+1; ++i )); do
        chr=$(printf '%d' \'"${1[$i]}")
        hash_val=$(( hash_val * 32 - hash_val + chr ))
    done
    echo "$hash_val"
}

this might be zsh specific given the whole string char access.

for bash cucks, just change ${1[$i]} to ${1:$i:1}
