Functions

decrypt

decrypt(text: string, key: string): Promise<string>

- Defined in lib/support/crypto.ts:48
Decrypt a base64 encoded text string.

Parameters
- text: string
  
  Base64 encoded string to be decrypted
- key: string
  
  Secrey key/passphrase to use to decrypt, must be the same as the one used to encrypt
Returns Promise<string>

UTF8 encoded string of decrypted text

deriveKey

deriveKey(key: string, length?: number): Promise<Buffer>

- Defined in lib/support/crypto.ts:67
Create an encryption key of length length derived using a CPU and memory intensive algorithm. The key is used directly and hashed to generate the salt for the derivation process.

Parameters
- key: string
  
  Key used to derive encryption key
- Default value length: number = algoKeyLength
  
  Length of derived key
Returns Promise<Buffer>

Encryption key of length length

encrypt

encrypt(text: string, key: string): Promise<string>

- Defined in lib/support/crypto.ts:32
Encrypt a text string and return is base64 encoded. The key is used to derive a suitable key and initialization vector.

Parameters
- text: string
  
  String to be encrypted
- key: string
  
  Secrey key/passphrase to use to encrypt
Returns Promise<string>

Base64 encoded string of encrypted text
