I have found two mistakes in stickynotes.py, but I have installed old Crypto module which has slightly different way of encrypting/decrypting.
The first one is that it refuses to create encrypted stickynote from empty node which is, according to the documentation, proper way to create encrypted stycky note. @g.command('stickynoteenc') def stickynoteenc_f(event, rekey=False): """ Launch editable 'sticky note' for the encrypted node """ if not encOK: g.es('no en/decryption - need python-crypto module') return if not __ENCKEY[0] or rekey: sn_getenckey() c = event['c'] p = c.p v = p.v def focusin(): if v is c.p.v: decoded = sn_decode(v.b) if decoded is None: return if decoded != nf.toPlainText(): # only when needed to avoid scroll jumping nf.setPlainText(decoded) nf.setWindowTitle(p.h) nf.dirty = False def focusout(): if not nf.dirty: return enc = sn_encode(str(nf.toPlainText())) if v.b != enc: v.b = enc v.setDirty() # Fix #249: Leo and Stickynote plugin do not request to save c.setChanged(True) nf.dirty = False p = c.p if p.v is v: c.selectPosition(c.p) c.redraw() if rekey: unsecret = sn_decode(v.b) if unsecret is None: return sn_getenckey() secret = sn_encode(unsecret) v.b = secret // this is new - check if it is old note already encrypted if v.b: decoded = sn_decode(v.b) if decoded is None: return else: // creating new encrypted note decoded = v.b nf = mknote(c,p, focusin=focusin, focusout=focusout) nf.setPlainText(decoded) if rekey: g.es("Key updated, data decoded with new key shown in window") See the red colored code. The other mistake is in padding string. It is necessary to pad bytes not unicode strings. def sn_encode(s): s1 = s.encode('utf8') pad = b' '*(16-len(s1)%16) txta = AES.new(__ENCKEY[0]).encrypt(s1 + pad) # for old Crypto module # txta = AES.new(__ENCKEY[0], AES.MODE_EAX).encrypt(s1 + pad) # for pycryptodome txt = base64.b64encode(txta) txt = str(txt, 'utf-8') wrapped = textwrap.wrap(txt, break_long_words=True) return '\n'.join(wrapped) With this two changes it works for me although I get crashes if calling AES.new as in pycryptodome. The encryption / decryption itself must be handled separately to check if we have new or old Crypto module. The old one doesn't have AES.MODE_EAX. def get_encoder(): key = __ENCKEY[0] if hasattr(AES, 'MODE_EAX'): return AES.new(key, AES.MODE_EAX) else: return AES.new(key) # txt = get_encoder().encrypt(s1 + pad) # or # decoded = get_encoder().decrypt(s1) HTH Vitalije -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
