RSA DecryptionĮncryption with PHP: use phpseclib3\ Crypt\ PublicKeyLoader To disable this behavior do $cipher->disablePadding(). Keep in mind that phpseclib, by default, pads it's ciphertext's. Plaintext = unpad(crypt(ciphertext), AES.block_size) AES-128-CBC DecryptionĮncrypting a string using AES-128-CBC with phpseclib: use phpseclib3\ Crypt\ AES ĭecrypting that same string with Python: from Crypto.Cipher import AESĬiphertext = omhex( '10f42fd95857ed2775cfbc4b471bc213')
