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.

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.
