ucryptolib – Encrypted password

Class

class ucryptolib.aes
classmethod __init__(key, mode[, IV])

Initialize password object, suitable for encryption / decryption. Note: After initialization, the password object can only be used for encryption or decryption. Does not support running decrypt() after encrypt().

Parameter:

  • key Encryption / decryption key (similar to bytes)

  • mode :

    • 1 (Or ucryptolib.MODE_ECB if present）Electronic Code Book(ECB)
    • 2 (ucryptolib.MODE_CBC if present）
    • 6 (Or ucryptolib.MODE_CTR if present) (CTR)

  • IV CBC mode initialization vector

  • For counter mode, IV is the initial value of the counter

encrypt(in_buf[, out_buf])
encrypt in_buf. If out_buf is not given, return the result as a newly allocated bytes object.

Otherwise, the result is written to the variable buffer out_buf. in_buf and out_buf can also refer to the same variable buffer, in this case, the data is encrypted in place.

decrypt(in_buf[, out_buf])

Similar to encrypt() , but for decryption.
