| Title: | Key Derivation Functions for R Based on Scrypt |
|---|---|
| Description: | Functions for working with the scrypt key derivation functions originally described by Colin Percival <https://www.tarsnap.com/scrypt/scrypt.pdf> and in Percival and Josefsson (2016) <doi:10.17487/RFC7914>. Scrypt is a password-based key derivation function created by Colin Percival. The algorithm was specifically designed to make it costly to perform large-scale custom hardware attacks by requiring large amounts of memory. |

scrypt is an R package for working with scrypt. Scrypt is a password-based key derivation function created by Colin Percival. The algorithm was specifically designed to make it costly to perform large-scale custom hardware attacks by requiring large amounts of memory.

The scrypt package can be used for hashing and verifying passwords, or encrypting and decrypting data. Additionally, the scrypt function can be used directly.

hashPassword, verifyPassword and scrypt
Hash a password
hashPassword(passwd, maxmem = 0.1, maxtime = 1)hashPassword(passwd, maxmem = 0.1, maxtime = 1)
passwd |
password to hash |
maxmem |
max memory percent (default 0.1) |
maxtime |
max cpu time (default 1.0) |
base64 encoded hash
# Hash password using default parameters hashPassword('passw0rd') # Hash password with custom parameters hashPassword('passw0rd', maxmem=0.25, maxtime=1.0)# Hash password using default parameters hashPassword('passw0rd') # Hash password with custom parameters hashPassword('passw0rd', maxmem=0.25, maxtime=1.0)
Verify a hashed password
verifyPassword(hash, passwd)verifyPassword(hash, passwd)
hash |
base64 hash to verify |
passwd |
password to verify |
TRUE if password matches hash, otherwise FALSE
# Hash password using default parameters hashed <- hashPassword("password") # verify invalid password verifyPassword(hashed, "bad password"); # verify correct password verifyPassword(hashed, "password")# Hash password using default parameters hashed <- hashPassword("password") # verify invalid password verifyPassword(hashed, "bad password"); # verify correct password verifyPassword(hashed, "password")
