Hashing¶

Cryptographic digest and password KDF hashing.

Digest Hashing¶

Compute a cryptographic digest of an input string. All digest endpoints share the same request and response format.

POST /api/v1/hash/md5¶

POST /api/v1/hash/sha1¶

POST /api/v1/hash/sha256¶

POST /api/v1/hash/sha512¶

Parameters

Name	In	Required	Description
`input`	body	yes	The string to hash

Example

curl -X POST https://api.apicrate.io/api/v1/hash/sha256 \
  -H "X-API-Key: $KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "hello world"}'

{
  "algorithm": "sha256",
  "hash": "b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9"
}

Password KDF Hashing¶

Derive password hashes using industry-standard key derivation functions.

POST /api/v1/hash/bcrypt¶

Hash a password with bcrypt.

Parameters

Name	In	Required	Description
`input`	body	yes	The password to hash
`rounds`	body	no	Cost factor (default 12, range 4–31)

Example

curl -X POST https://api.apicrate.io/api/v1/hash/bcrypt \
  -H "X-API-Key: $KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "my-secret-password", "rounds": 12}'

  "algorithm": "bcrypt",
  "hash": "$2b$12$LJ3m4ys3Lz0YHDtP6Wi0ceB7eat/lnS5z3FGbO2rGkSMo0In5muS6"
}

POST /api/v1/hash/scrypt¶

Hash a password with scrypt.

Parameters

Name	In	Required	Description
`input`	body	yes	The password to hash
`n`	body	no	CPU/memory cost parameter (default 16384)
`r`	body	no	Block size (default 8)
`p`	body	no	Parallelism factor (default 1)

Example

curl -X POST https://api.apicrate.io/api/v1/hash/scrypt \
  -H "X-API-Key: $KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "my-secret-password"}'

{
  "algorithm": "scrypt",
  "hash": "$scrypt$ln=14,r=8,p=1$c2FsdHNhbHQ$..."
}

POST /api/v1/hash/argon2id¶

`parallelism`	body	no	Degree of parallelism (default 4)

Example

curl -X POST https://api.apicrate.io/api/v1/hash/argon2id \
  -H "X-API-Key: $KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "my-secret-password"}'
