b2b

b2b is a command line tool to calculate BLAKE2b hashes based on libsodium and sodiumoxide.

``` b2b 0.1.0 Dave Parfitt diparfitt@gmail.com Calculates BLAKE2b checksums using libsodium

USAGE: b2b [FLAGS] [OPTIONS]

FLAGS: --base64 Display the value in RFC 4648 standard base64 encoding instead of hex -h, --help Prints help information -V, --version Prints version information

OPTIONS: -l, --length Size of hash in bytes, default: 32

ARGS: Input filename or - to read from ```

Installing

You'll need the cargo command from Rust and libsodium-dev installed.

cargo install b2b

If this fails because Cargo can't find libsodium (typically OSX), try setting the following environment variables to the appropriate values:

```

SODIUMLIBDIR must end with /lib

export SODIUMLIBDIR=/some/path/ending/with/lib export LDLIBRARYPATH=$LDLIBRARYPATH:$SODIUMLIBDIR cargo install b2b ```

Building from source

b2b is written in Rust.

Ubuntu

TODO: untested

apt-get install libsodium-dev cargo build

OSX

brew install libsodium export SODIUM_LIB_DIR=`brew info libsodium | grep Cellar | awk '{ print $1 }'`/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SODIUM_LIB_DIR cargo build
