# make-my-life-easier
A couple scripts I use on a daily basis to make my life easier.
They are all ready to go command line tools :)
## Installation
### Preliminary
- `go` needs to be installed, version 1.12 or above
### Pulling the code
- retrieve the code from the repo
-- go get github.com/benjaminch/make-my-life-easier
- or install the module + code
-- go install github.com/benjaminch/make-my-life-easier
### Launching the code
- run `go run mmle.go help`
## Price encryption / decryption (Google Private Data specs)
### Usage examples
#### Help
```
go run mmle.go help
usage: mmle [] [ ...]
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-v, --verbose Verbose mode.
Commands:
help [...]
Show help.
price-encryption []
Encrypt a price using a given algorithm.
price-decryption []
Decrypt a price using a given algorithm.
hex-key-generator []
Generate a random hex key of the specified length (by default: 64)
```
#### Decrypt only
The command line below will try to decrypt the encrypted price passed in command line.
```
go run mmle.go price-decryption [YOUR_EKEY] [YOUR_IKEY] [ENCRYPTED_PRICE]
```
Details:
```
usage: mmle price-decryption []
Decrypt a price using a given algorithm.
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-v, --verbose Verbose mode.
--algorithm=google Name of the algorithm
--keystype=hexa Keys type
--keysb64 Keys are base 64.
--scale=1000000 Price scale factor
Args:
Encryption key
Integrity key
Price to decrypt
```
#### Encrypt only
The command line below will try to encrypt the clear price passed in command line.
```
go run mmle.go price-encryption [YOUR_EKEY] [YOUR_IKEY] [CLEAR_PRICE]
```
Details:
```
usage: mmle price-encryption []
Encrypt a price using a given algorithm.
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-v, --verbose Verbose mode.
--algorithm=google Name of the algorithm
--keystype=hexa Keys type
--keysb64 Keys are base 64.
--scale=1000000 Price scale factor
--seed="" Seed
Args:
Encryption key
Integrity key
Price to encrypt
```
### Verbose mode
The verbose mode describle the process step by steps.
```
go run mmle.go price-encryption [YOUR_EKEY] [YOUR_IKEY] [CLEAR_PRICE] --verbose
Verbose activated

## Hexa keys generation
### Usage examples
The command line below will generate an hexa key of the desired length (by default, 64 bytes).
```
go run mmle.go hex-key-generator
go run mmle.go hex-key-generator --keylength=32
```
Details:
```
usage: mmle hex-key-generator []
Generate a random hex key of the specified length (by default: 64)
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-v, --verbose Verbose mode.
--keylength=32 Key Length
```
