RSA utilities: deterministic key generation (reproducible from a seed), flexible private-key parsing (PEM/DER/base64 variants), and chunked RSA-OAEP encrypt/decrypt for arbitrary-length data.
KeyOpts struct — { Bits, Exponent, Seed []byte }.GenerateDeterministicRSAPrivateKey(opts KeyOpts) (*rsa.PrivateKey, yaerrors.Error) — the same seed + bits + exponent always yields an identical key.ParsePrivateKey(s string) (*rsa.PrivateKey, yaerrors.Error) — accepts PEM (PKCS#1/PKCS#8), base64-of-PEM, or base64-of-raw-DER.DeterministicReader struct + NewDeterministicReader(seed []byte) *DeterministicReader — HMAC-SHA256-based deterministic byte stream, an io.Reader.StripCRLF(s string) string.Encrypt(plaintext []byte, public *rsa.PublicKey) ([]byte, yaerrors.Error) — RSA-OAEP (SHA-256), auto-chunks plaintext (190 bytes/chunk for 2048-bit keys).Decrypt(ciphertext []byte, private *rsa.PrivateKey) ([]byte, yaerrors.Error) — reverses the chunking (ciphertext length must be a multiple of the key's block size).GenerateDeterministicRSAPrivateKey requires a high-entropy Seed — a weak seed fully compromises the key. Bits must be even and >= 512.DeterministicReader and GenerateDeterministicRSA* are not concurrency-safe — one instance per goroutine.Encrypt/Decrypt don't handle transport encoding (no base64) — apply that at the edges yourself (see yaginmiddleware for an example combining it with yaencoding.ToString). Depends only on yaerrors.Index of every GoYaCodeDevUtils utility package (config, errors, logging, caching, rate limiting, backoff, hashing, gzip, RSA, feature flags, FSM, thread-safe collections, locales, Telegram bot stack) with a pointer to each package's own skill. Use before hand-rolling infrastructure code GoYaCodeDevUtils may already provide.
High-level Telegram bot framework on top of gotd/td - router/dispatcher with filters and middleware, FSM-aware routing, per-user localization, sequential-update scheduling, and a message-send queue. Use as the starting point for any Telegram bot.
Thin wrapper around gotd/td's telegram.Client adding background-connect-with-retry, bot-token authorization, updates.Manager wiring, and SOCKS5/MTProto proxy helpers. Use for direct low-level Telegram client control instead of raw gotd/td.
Redis-backed persistence for gotd/td's updates.Manager state (pts/qts/seq/date via RedisJSON) plus channel/user access-hash bookkeeping, and a GORM/AES-encrypted session-storage layer. Use for any yatgclient/yatgbot state or session persistence.
Generic pluggable key-value cache abstraction with interchangeable in-memory and Redis backends, hash-oriented API. Use for any caching/session-store need instead of hand-rolling a map or a bare redis.Client call.
Loads JSON locale files into a nested key-tree with lookup, {placeholder} formatting, JSON serving, language-tag normalization, and Go-struct codegen. Use for any i18n/localization instead of hand-rolled JSON locale loading.
